The JST-connector and 3.3v system voltage make this a great development tool for portable devices, simply plug in a Li-Poly battery and you’re ready to go. Wireless sensor networks and communication are made easy by the on-board XBee socket. The ATmega32U4, running at 8MHz, makes it possible for you to use the on-board USB jack not only to charge a connected Li-Poly battery but to actually program the device! Because this board uses a similar bootloader to the one on the Pro Micro, you will need to download and install the special software driver below. There’s also a board definition add-on for the Arduino IDE which will add support for this board. We’ve updated this to the latest version of the 32U4 firmware, see the firmware note in the documents below! Note: See the GitHub link below for support with the Arduino IDE.
