Components

:?: Most of my component recommendations are in Buyer's Guide.

Microcontroller Development Boards

Espressif ESP32

FIXME

Nordic nRF52840

STMicro STM32WL

STM32WLEx product page; note that this MCU has an integrated Semtech SX1262.

Meshtastic firmware support is still WIP (booting and functional, but no writeable configuration storage); see [Board]: STM32WL (Seeed Studio Wio-E5) #2539

LoRa Modules

:!: Note: Meshtastic only supports modules with SPI connectivity; UART modules are not supported.

Semtech SX1262
