Features

– Powerful CPU, BLE and state of the art WiFi radio. 1KM Wifi Range
– Can also double up as Nano LoRa gateway
– MicroPython enabled
– Fits in a standard breadboard (with headers)
– Ultra-low power usage: a fraction compared to other connected micro controllers

NOTE: Using the LoRa radio without the external antenna can lead to damage of the device and is therefore not recommended.
