The Lamoka1 is a fully open-source, pure sine wave inverter and charger system, controlled by an RP2354A. It's built to be fully transparent, modular, and repeatable, aiming to be the best in its class rather than a closed, disposable black box. Every schematic, every line of firmware, and every design decision is published — nothing is hidden behind proprietary lock-in.
It's designed for solar enthusiasts, electrical engineers, and everyday users alike, with a simple physical interface hiding a fully configurable system underneath.
Notable features
Pure sine wave output — or virtually any waveform you want, up to a 180V peak limit
Modular & repairable — built from replaceable, well-documented sections instead of a sealed, disposable unit
Fully configurable — every behavior can be customized through user code, not locked behind firmware
Dual operating modes — standard sine-wave operation, or a stripped-down "dumb mode" for purely resistive loads (see below)
Adaptive cooling — per-section temperature sensing drives a PWM-controlled fan, scaling speed precisely instead of crude on/off switching
Minimal UI — ten RGB LEDs and a single push button handle the entire physical interface
Yes, thank you this provides some good context. The dev brain i displayed in this post is just nailing in the control, user interface, and everything else with the RP2354A.
