Pro Micro ATmega32U4 for Arduino Nano

Tscinbuny Pro Micro ATmega32U4 5V16MHz Support for Arduino Nano W/ 2 Row Pin Header for Leonardo Mini USB Interface MCU Development Board Features:ATMEGA32U4 runs at 5V/16MHzSupported I/O IDE V1.0.1Micro USB interface programming on the board4 10-bit ADC pins12 digits for Arduino (5 PWM capability)Rx and Tx hardware serial connection illustrate:  This small board does all the neat for Arduino skills: 4-channel 10-bit ADC, 5 PWM pins, 12 DIO, and hardware serial connection Rx and Tx you are familiar with. Running at 16MHz and 5V, this committee will remind you of Arduino-compatible boards you like, but this little guy can go anywhere. There is a voltage regulator on the ship, so it can accept voltages up to 12VDC. If you are supplying an unstable power supply board, be sure to connect to the "RAW" not the VCC pin. This latest version fixes silk errors so that pin 14 is the correct marking. We also added a PTC fuse and diode to protect the power supply circuit and corrected the RX and TX LED circuits
