Development Board Compatible with Arduino Pro Micro

Overview

This development board is the best choice for electronic projects that require a small space occupied by the microcontroller.

It can communicate with ATMEGA32U4 microcontroller via USB, so it can be easily programmed without the use of a special programmer. This board also features a micro-USB connector.

This small board does all the neat Arduino skills: 4-channel 10-bit ADC, 5 PWM pins, 12 DIO and hardware serial connection Rx and Tx you are familiar with. It runs at 16MHz and 5V, and accepts voltages up to 12VDC. If you are supplying an unstable power board, be sure to connect to the "RAW" not 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.
