1 The Board

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