BS Micro is based on the ATmeag32U4 Micro controller board. It owns 14 general purpose digital input/output pin (five can be used as a PWM output, 6 can be used as an analog input). On board with 16 MHZ crystals and A USB – type A interface based on PCB. In addition to A 3.3 V power supply output independently, it will not affect the work of MCU power output, the output power depends on the USB port power supply capacity, but is not higher than 1.5 A. Bat has burn Arduino bootloader, so it is compatible with the Arduino IDE.
Although it is small in size, but it has rich interface, make it not only has the function of the traditional controller, and realize the function of the mouse, keyboard on the computer, a serial port function, and can realize communication with computer directly.
It like most other MCU control board is a big difference between programming does not need additional use programmer, directly from the USB programming. This is not only convenient, stable and reliable, also save the expense of a programmer.
