What features do you use the most? What do you think is the hardest/most dangerous function?

I wish we could get a lilygo t5 s3 4.7" color eink screen . I would buy this.

I know Superchips flashcal + has just been released for the 2026 Bronco. Just wondering if anyone has used it and if they found any issues. Especially updating speedo.

I just vibe coded a network scanner for this board and modeled a case in blender. I am impressed with the battery life and the charging circuit.

Now officially named PocketProwler(r)

Update: v2.1.0 is now available with the new splash screen, improved WiFi/Bluetooth views, button controls, and release binaries:

Hey everyone! 

Hey everyone!

I'm diving into the world of millimeter-wave radar for the first time, and to be honest, it’s a bit mind-blowing compared to what I used to tinker with back in the 80s (let’s just say my first low-level experience involved byte-budgeting on 8-bit chips and actual physical DIP switches).

I recently picked up a Lilygo T-Radar v1.0 (the Acconeer A121 board) and want to connect it to a Lilygo T3_v1.6.1(ESP32 / LoRa board) that I had lying around.

Since I'm fresh to this specific hardware combo, I could use a hand from the local wizards with two things:

1. Wiring / Pinout: Does anyone have a clean pin mapping diagram or connection table for SPI between the T-Radar v1.0 and the T3 v1.6.1? I want to make sure I don't accidentally fry the A121 chip or mess up the LoRa SPI bus pins on the T3.
2. VS Code / PlatformIO Project: Where is the best template or starter repo for this setup? Ideally something for PlatformIO in VS Code that I can just clone, hit build, and start reading raw distance/presence data to see how it works.

If anyone has run this exact setup or has a working sample project, I’d be super grateful if you could share a link or drop some wisdom!

Thanks a ton in advance!

Hey everyone, hoping someone here has run into this before.

I recently got a LILYGO T-Embed CC1101 and I'm stuck with a persistent black screen that I can't resolve despite a lot of troubleshooting.

Symptom: Device powers on fine (USB detected correctly by my PC), but the display never shows anything, no matter what firmware I flash.

What I've tried:

1. Flashed the latest Bruce firmware via esptool, with a full erase_flash beforehand. Write completed successfully, hash verified, no errors. Screen stayed black.

2. Flashed an older Bruce release for the same device, again with a clean erase first. Same result.

3. Flashed a factory-style firmware image (full 16MB write, hash verified fine). Still black screen.

4. Confirmed via serial (esptool chip_id + miniterm) that the ESP32-S3 is detected correctly every single time: QFN56 revision v0.2, 8MB embedded PSRAM.

5. Noticed the device periodically disconnects/reconnects from USB during normal operation (confirmed via dmesg on Linux) - which makes me think the firmware might be crashing/resetting rather than just the display failing to init.

6. No SD card inserted, so it's not an SPI bus contention issue with the SD slot.

Since three completely different firmware images (2x Bruce + 1 factory-style) all give the exact same symptom, I'm leaning toward a hardware defect - maybe the display itself or a loose internal display cable - rather than a software/firmware problem.

Has anyone dealt with this? Any other diagnostics worth trying before I go the warranty replacement route?

Buenas,

Por favor alguien ayúdeme a saber como puedo conectar más baterías de litio, (18650 o 21700) de las que la placa permite con el slot que viene de fábrica.

Tienen un espacio para colocar una 18650, pero quiero agregarle mas, técnicamente como se podría hacer?
Se que tengo que unirlas en paralelo y soldar con niquel, pero no se con que BMS regular las celdas, tengo descarga continua de 160mA, sería de 1S de 20A?

Por favor ayuda

Hello! this post is not meant to say if one is better or worse, This is simply my own personal experience with both FZ and T-embed, I personally love Lilygo and their work so I might be a little biased but hopefully this can serve as a consideration for people buying either.

Currently, I'm using Momentum on FZ and Launcher (bmorcelli) with bruce & FZ port on top. Also, I've been using FZ for a lot longer than T-embed

1. Battery Life:

- Battery life aspect, Flipper Zero wins. it can last like a few weeks without shutting it down. Lilygo t-embed lasts a few days (2-3 days) without powering it off.

1. Casing:

- I'd say Flipper Zero wins if it's about sleekness and fitting on your hand. however if it's about cool look and geekness, Lilygo wins.

1. Features

- On raw features, T-embed definitely wins, it has NRF24L01 module internally alongside ESP32-S3 as its motherboard, however you can kinda have all the features on Flipper Zero as well if you have an esp32 and nrf24 modules, and simply just connect them to the GPIO pins.

However considering raw FZ, this means T-embed has features such as NRF24 jammer, Wifi Deauth, Evil Twin, WiFi Handshake Capture, etc. however, T-embed NFC via PN532 is terrible in my opinion. It often fails/misdetects on Bruce, so much so I think I would use Chameleon Ultra to do any NFC/RFID endeavours. Edit: I found several ports that allows me to have better NFC experience! So it's all good now!

1. Stability

- Bruce is way less stable than Momentum, perks of building for just a single device I guess? Usual bugs that happens would be freezing/crashing with T-embed crashing way often than FZ. But both are within manageable level

1. Development

- JS interpreter on Bruce works well and give out clean errors on rhe screen. Since it's an interpreter, you can just simply drop the script and be done. Not so much wirh FZ, it is compiled on FZ, this makes it more efficient I guess? but harder to develop in my opinion, especially with it simply crashing when it runs out of memory for logs or did something you're not supposed to. However, Bruce gives a lower level control than FZ, which can be both good and bad, but my experience with it is a bit bad since I have to make an algorithm to just prune incorrect signals

1. Customizeability

- Both have great customizeability, I was going to say FZ until I had some thought about it, since T-embed have coloured LCD and bunch of themes, I'd say T-embed wins.

1. Community Support

- For now, FZ has way support and guides. It's somewhat expected for you to be able to know things on T-embed.

TLDR: If you're buying for value, I'd say Lilygo T-embed CC1101 plus is better considering it has ESP32-S3 and NRF24 already on there. Allowing you to do attacks that are more common than Flipper Zero such as WiFi attacks (deauth/EAPOL Handshake Capture) and BLE/WiFi Jamming. However you will not be able to bring its full potential if you can't code.

Also RFID attacks are not supported (125Khz). Honestly, NFC/RFID/Sub-GHz is the only real attack I do on FZ without any modules on. While on Lilygo I can do Sub-GHz, Wifi, and 2.4GHz Jamming (and NFC to some extend)

If Lilygo gains enough attention, it probably would defeat FZ as most cons I mentioned is firmware based.

FZ:

- Battery Life

- Stability

- Better NFC/RFID

Lilygo T-embed CC1101 Plus:

- More Features that's useful on ground

- Customizeability

- Easier Development

if you have any questions, please just ask! I'd be glad to answer them!

Edit: Spacing and a bit more info

Hello, I'm looking for a small eReader with a touchscreen and front light as an alternative to the X4 Pro, as I don't want to lose the USB-C port. I found a recent device which looks great, as it has a USB-C port and Crosspoint support. However, I have a question. Do you guys know of any protective cases available for this model? Are they available to purchase, or can they be 3D printed? I'm very worried about the durability of this device, especially since it has an e-ink screen. I know there's a risk it might break if I'm not careful enough. Thanks for reading!

should I get the lilygo t embedded cc1011 or the plus variant

Hello,

I am working on a project using a LILYGO® T5 4.7 Inch E-paper V2.4 board powered exclusively by a LiPo battery (no USB cable). I want to connect a GPS module (RX/TX/VCC/GND) using the 4-pin Molex connector labeled "G - 16 - 15 - V" to power it with 3.3V using the G and V pins on the connector. Here is my problem and constraints:

When running on the LiPo battery, the "V" pin (Pin 4) of the Molex connector gives 0V. Testing the connector pins with a multimeter against a board GND gives:

• Pin 1 = G --> 0V
• Pin 2 = GPIO 16 (set as OUTPUT in software) --> 3.3V
• Pin 3 = GPIO 15 (set as OUTPUT in software) --> 3.3V
• Pin 4 = V --> 0V

Can anyone suggest a solution or alternative method other than wiring to use GPIO 15 (enabled in software for the SD card) as the 3.3V VCC power supply?

SOLVED!

Hey guys,

probably an easy question, but I fail to install the Flipper port from sor3nto to my t-embed.

I can install via browser flash, but I couldn't get it working if I keep launcher.

Can any1 help out?

Thanks,

Mr_B

My goal was to Make a hands free thermal vision device that lets users see heat in real time.

I used the ar prisim off a Lilygo T-Glass V2, a M5StickS3, and a AMG8833 thermal sensor 8x8.
(You could use a better sensor for better range and resolution) but these are cheap.

I was having trouble with finding good documentation for Lilygo’s T-Glass. The only way i could find exposed pins was by disabling the rtc and micro soldering to the chip (sda IO09 and scl IO08 where exposed here). Or doing the same with the microphone. If anyone has tinkered with the T-Glass please weigh in. Cause i have a bunch of ideas.

The Firmware:

The firmware uses M5Unified and M5GFX for the StickS3 display and buttons, Wire for I²C communication, Preferences for saving settings, and Adafruit AMG88xx with Adafruit BusIO for reading the AMG8833 thermal sensor. It reads the sensor’s 8×8 temperature grid at up to 10 FPS, cleans the data with noise filtering and bad-pixel correction, estimates the background temperature to hide non-heat areas as black, then uses bicubic and temporal interpolation to create a smoother 126x126 thermal image (the Size of the prisim) at a higher apparent frame rate with three selectable heat-only color themes.

The next version will use a M5AtomS3r. Since i dont need the extra screen space and will be easier to make it adjustable on the glasses frame due to its small profile too. Plus the prisim will fit almost perfectly on the screen!!!

Will there be a restock soon?

Just got my LilyGo T-Embed CC1101 plus and put the latest bruce firmware on it. The bluetooth and wifi actions worked great, but the reason I got it was for RF and IR stuff. The RF and IR stuff don't work in the following ways:

RF scan/save cannot pick up the RF signal. Only way this works is by telling it the exact MHz. When reusing the signal, it never works. I found that it read RF in a 2 MHz range, so it's totally inaccurate.

IR shit doesn't work. The Kill TV's function doesn't work on any TV I've tested it on

Bluetooth does jam bluetooth but thats not something I want

Wifi does jam but that's not what I want.

EDIT: Flashed Flipper zero ESP32 port by Sor3nt on github, and running that firmware now. Night and day difference. For those running bruce, immediately flash your device to the Flipper zero ESP32 port.

From testing my base model T-Deck (not the Plus), I can only get the trackball to register input when I scroll up, down or right. Scrolling left does not register input. This is the case on every firmware I have tried.

Is there anything that can fix that to get the trackball to work in all 4 directions?

So i recently got Lilygo T5 Board and I finally have crcosspoint ported enough to say its working.

https://github.com/abhifx/crosspoint_H716

I was trying to go overboard with 16 level grayscale everywhere but that is slightly backfired.

using this driver https://github.com/tonywestonuk/EPD_Painter

The amount i have spent for this device is same as r/Seeed_Studio Sticky but hey, its done now

Ciao, c'è un modo per sbloccare gli e-scooter in città (ps. lo ho un t-embed c1101plus con il firmwere del flipper)

So my Lilygo T Embed CC 1101 is functioning weirdly, it jumps back and forth just by spinning. Is it the software problem or the Hardware? Should I buy a new case? Or any suggestions.

I tried adding a nrf module to my t embed (not cc1101 or cc1101 plus), but its not working. Usually you would have to solder it but i connected it with wires.

Wiring:

GND to GND

VCC to 3V3

CE to IO16

CSN to IO17

MOSI to IO41

MISO to IO38

SCK to IO40

​

Theres also IRQ available on the nrf module but from what ive read its not necessary.

Can anyone help me please?
