1 The Board

As all Nano form factor boards, Nano 33 BLE Rev2 does not have a battery charger but can be powered through
USB or headers.
NOTE: Nano 33 BLE Rev2 only supports 3.3 V I/Os and is NOT 5V tolerant so please make sure you are not directly
connecting 5 V signals to this board or it will be damaged. Also, as opposed to other Arduino Nano boards that
support 5 V operation, the 5V pin does NOT supply voltage but is rather connected, through a jumper, to the USB
power input.
