Product Data Sheet

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.
