From the project
Adaptador USB->SPI (CH341F) para modulos LoRa EBYTE E22P-868M30S de 1 W con meshtasticd
Adaptador USB → SPI para usar un módulo LoRa EBYTE E22P-868M30S (SX1262 + PA, 30 dBm / 1 W) con meshtasticd en un PC o una Raspberry Pi, sin necesidad de GPIO.
El puente es un CH341F en modo UIO, que es el que soporta el driver libch341-spi-userspace de Meshtastic. Un multiplexor TPS2115A conmuta automáticamente entre la alimentación del USB y la de un jack DC, de modo que el módulo puede transmitir a plena potencia sin sobrecargar el puerto del ordenador.
