STM32L microcontroller board with LoRa transciever and IPX connector

This board allows communication with LoRa protocol via STM32L microcontroller. STM32L is a powerfull 32-bit microcontroller with low power consumption and with 64kB flash memory and 8kB RAM memory, set to work on 16MHz. It contains lots of hardware: 12-bit ADC, SPI, UART, ICA, 7 timers… Board does not come with bootloader, so you need to use a standard STLINK Programmer to put a new code on a microcontroller.

Except STM32L, there is RFM95W LoRa transciver. Thanks to it this board can send and recieve data from LoRa gateway or from the other board like this. To reach maximum distance there is an IPX connector to connect your antennas. Board has a connector and charger for a standard li-ion battery. A very important thing about LoRa is the low power consumption, and this board definitely makes it possible: the power consumption in the sleep state is only 4.5μA.

This board comes with soldered easyC adapter and enables simple connections. You can find more about easyC at this link.
