Notes

Power

Do not use the 3.3V pin in combination with the Vin pin to supply the device as this will damage the voltage regulator on the board.

Antenna placement

Always attach the appropriate antenna when using a wireless connection (LoRa / SigFox). For WiFi / BLE, it is not mandatory to use an external antenna when you did not explicitly specify this in your code.
