From the project
An Adafruit Feather-sized STM32 development board with integrated 868 MHz LoRa radio.
An Adafruit Feather-sized STM32 development board with integrated 868 MHz LoRa radio.
As I was scrolling through ST Microelectronic's website (as one does), I found the perfect match: the STM32WLE5 family of microcontrollers. They offer an improved LoRa solution - with up to +22 dBm output power - in a sleek package, with an integrated, low-power STM32 microcontroller. I knew I had to try making something with it.
