Build resources

Build it from the project documentation linked in Sources. Components and assembly are required.

Notes

LoRa projects require extra GPIO connections soldered to the radio; replacing the ESP32-C6’s ESPHosted firmware for Meshtastic also affects Wi-Fi and Bluetooth.[9] The radio uses an Ai-Thinker Ra-01SH module.[10] The SMA connector is supplied separately and must be soldered.[2] Designed by the WHY2025 Badge Team.[2]
