Keyes Pro Micro is a mini microcontroller board developed based on the Atmega32U4 chip. This development board is compatible with all Arduino features and techniques. It includes: 4 analog inputs, 5 PWM (Pulse Width Modulation) pins, 12 digital input/output ports, and hardware serial connections for Rx and Tx. It operates at a voltage range of 3.3V, with a working frequency of 16MHz. The board can accept an external power supply voltage of up to DC 9V. To supply power, connect the positive terminal of the power source to RAW. We have also added a PTC fuse and diodes to protect the power circuit. When selecting a test program, ensure that the Arduino IDE version is 1.0.3 or above.
