The Vin range of the Arduino Nano 33 follows the current Nano series. Vin accept wide range 4.5V-21V is convenient to use, i.e. 9V battery.
In some projects, small LiPo batteries may be connected, in which case voltage adjustment and charging must be handled externally.
nano9jira is a whale-shaped, add-on board that enables 3.7V LiPo battery connectivity and charging function to Nano 33.
In addition, extra port for battery operated motor / servo, or sensor is added.
*Since charging uses 5V from the USB port, please short the VUSB land on the Nano 33.
