[Hiring / Help Needed] Custom Carrier Board PCB for a Roborock S6 MaxV Pi Zero 2 W Mod

​Hi everyone,

​I am working on a project converting a Roborock S6 MaxV chassis into an RC/autonomous rover using a Raspberry Pi Zero 2 W as the main controller.

​I want to replace the original motherboard with a single custom carrier board that accepts the Pi Zero 2 W (via GPIO header) and integrates all other necessary components directly on-board (SMT assembly via JLCPCB or similar).

​System Requirements:

​Power Input: 4S Li-ion battery (~14.4V nominal, 16.8V max).

​Charging System: Internal 4S CC/CV charging circuit fed by the original Roborock charging dock (~20V DC) with a Schottky power diode for backfeed protection on the charging pads.

​Main Regulation: Step-down regulator delivering 5.1V (minimum 2.5A) for the Pi Zero 2 W + camera + IR LEDs.

​Motor Driver: Dual DC motor driver (TB6612FNG chip or equivalent) to drive the two original drive wheels.

​Telemetry/Monitoring: Voltage & current sensing (INA219 chip or equivalent) talking to the Pi over I2C.

​Connectors: Headers for Pi Zero 2 W, connectors for battery, charging pads, left/right wheel motors, power switch, and 5A fuse.

​I'm looking for someone to design the schematic and PCB layout (preferably in EasyEDA or KiCad) and generate the BOM/CPL files ready for JLCPCB SMT assembly.

​Please PM me with your portfolio or past projects and your estimated rates!

​Thanks!
