Keyestudio Atmega32U4 Pro Micro Microcontroller Development Board

KEYESTUDIO PRO MICRO is a microcontroller board based on the ATMEGA32U4-MU. It is an easy-to-use open source hardware.

It has 18 digital input/output pins (of which 5 can be used as PWM outputs), 9 analog inputs, a 16 MHz crystal oscillator, and a micro USB connection.

It contains everything needed to support the microcontroller; simply connect it to a computer with a USB cable to get started. 

The keyestudio PRO MICRO can be powered via the micro USB connection, or via the interface RAW GND (DC 7-9V).

Note that the operating voltage of PRO MICRO is 3.3V.

The PRO MICRO differs from other Arduino boards using separate USB-Serial chip in that the ATMEGA32U4-MU has built-in USB communication, eliminating the need for a secondary processor.

It is easy to integrate this Micro in everyday objects to make them interactive.

To facilitate the physical design, the board is not welded with pin headers, so you can solder the pin headers by yourself. And the package includes 2pcs of yellow 1*12 2.54 straight pins and 1m black micro USB cable.
