Easily power your JeVois smart camera from a single-cell Lithium batter (3.7V nominal voltage) using this tiny converter.

Simply connect your Lithium battery to the input solder tabs on this converter, and connect your JeVois smart camera to the USB output port. Includes undervoltage (brown-out) protection to protect your Lithium battery from potentially harmful over-discharge. When the battery voltage is less than 2.7V, the load indicator LED will turn off.

Does not include any charging circuitry. You need to provide a charger for your Lithium battery separately (for example, R/C battery charger). Does not include short circuit or reverse polarity protection, handle with care.

Note: This accessory is intended for applications where you will not stream video out of your JeVois camera to a host computer, but instead will only stream text outputs over serial port to an Arduino. Hence, the mini-USB port of your JeVois smart camera will only be used to power the smart camera. Please see http://jevois.org/doc/UserConnect.html for more information.
