The Arduino Pro Micro

The Arduino Pro Micro is almost the same as the Arduino Pro Mini, with the only difference being an ATmega32U4. Unlike the Pro Mini, the new chip brings USB capability without the need for additional external components

This small yet extremely powerful Arduino board has all the great features you are familiar with. 4 x one 10 Bit Analog / Digital I/O's, 12 Digital I/O's of which 5 can be used as PWM. In addition, the Arduino Pro Micro also has hardware Serial Connections RXD and TXD. The Pro Micro also functions at 16 Mhz and needs 5 Volt DC as the power supply

This small but powerful board is suitable for almost any situation and can be used almost anywhere, onboard is also a voltage regulator so you can use up to 12 volts of voltage to power the board. use the port "RAW" instead of VCC

This latest revision also corrects a previous error where pin 14 was incorrectly labeled, in addition there is a PTC fuse and a Diode on the board against incorrect connection of the Pro Micro, the RXD and TXD LEDs have also been adjusted

The use of the available Shield for the Arduino boards is also possible, if you have to make a Headerboard yourself to place a shield, or connect the Shield via Module Wires, by keeping almost the same size as the Pro Mini has this Pro Micro one step ahead of its smaller brother, because the Arduino Pro Micro can be programmed via Mini USB.
