Description
Microduino Core USB is a very small (28 x 25.4 mm) electronic board based on the 8-bit Atmega32U4 microcontroller. Compatible with Arduino Leonardo, it features a USB connection, 20 digital input/output pins (8 of which can be used as PWM outputs), 6 analog inputs, 32 kB of Flash memory (4 kB used by the bootloader), 1 hardware serial port, 1 virtual USB serial port, a 16 MHz oscillator crystal, and a male/female connector for stacking modules. For programming, use the same Arduino IDE.
