Notes
V3.1 is a radio HAT for the Luckfox Lyra Ultra W, not a complete node; it uses meshtasticd on the external host.[1][5]
The maker says V3.1 retains V3’s radio design and changes I2C routing for the RTC and AHT20, so the V3 schematic identifies the shared E22P-915M30S radio path.[1][2] Ebyte rates this fitted module at 30 dBm (1 W) with at least 5 V supply.[3] An external GPS receiver is required; the GPS header is an expansion connection.[2] Meshtastic support follows the community Luckfox Ultra 1W configuration.[7]
