Device prototype with BLE and LoRa

A prototype board integrating an nRF52840 microcontroller with BLE, GNSS and LoRa communication using an SX1262. The board was used to collect location data in the field.

Despite the use of cheaper parts, the board was optimized for low power consumption, averaging below 15 µA in sleep mode and 75 µA with a LoRa transmission every 5 minutes.
