3.1.6 External Power

There are two ways to add external power to the AVR-IoT Cellular Mini board:
  1. Through the USB pin on the edge connector.
  2. Through the VMUX 100-mil pin header.
Warning: Before doing any hardware modifications, make sure the board is disconnected from USB, battery or external power.
Warning: When powering the board with an external source, make sure that the voltage is between 2.5V and 5.25V. Any voltage exceeding this may damage the board.
Warning: When using external power, make sure that the board is not connected to a battery or USB power. If it is, it may damage your board.
