Description The modular design to facilitate dismantling. It is a good choice to build prototype circuits. The board is similar to the previous board, they have the same function, the main upgrade from the classic ATMega328 to the latest ATMega32u4 controller controller. Not only can run the latest and greatest firmware, it may not be required FTDI Downloader can download the program, only you need a Micro-USB cable can. Ideal for wearable product design. Like classic board of aerial tricks, as the board left JST interface, powered by lithium batteries, lithium batteries can also be charged directly by the board. Flashed with arduino bootloader. PCB thickness: 0.8mm Outer diameter: 50mm MCU: Atmega 32u4 Notice that need to install driver in windows here.
