Notify me when its in stockThe Pro Micro development board compatible with Arduino features physical dimensions similar to the original Arduino® Pro Mini.
However, since it has an ATmega32U4 microcontroller IC, it also has additional features such as USB HID (keyboard/mouse emulation) that boards like the original Arduino® Leonardo and Arduino® Micro have.
Because the ATmega32U4 microcontroller has built-in USB communication capability, you can program the board by connecting it directly to your computer via USB without needing an external FTDI converter board like the Pro Mini.
The Pro Micro development board compatible with Arduino features 9 channels of 10-bit resolution ADC (analog-to-digital converter), 5 PWM pins, 12 digital I/O (input/output) pins, and RX and TX pins for hardware serial communication.
It operates at a speed of 16 MHz and 5V voltage. Thanks to the built-in voltage regulator on the board, it is possible to operate it with a supply voltage of up to 12VDC via the "RAW" pin.
