Notes
V0.3.5 replaces the earlier solar charger with a CN3791.[1] Designed by valzzu around a Pro Micro-compatible nRF52840 board and Ebyte E22-900M30S module.[1][3]

- Requires a battery; it is not designed to run directly from a solar panel without one.[1]
- Battery-protection fix: the maker corrected a capacitor placement error in PCB V0.3.5.6 (and V0.4.6 for the separate integrated-MCU design). Check the PCB revision when ordering or building.[1]
- DIY manufacturing files and optional assembled boards are available.[1]
