At the heart is an ATmega32U4, the same microcontroller is found on the popular Arduino Leonardo. The 4Duino-24 is powered by the feature-rich PiCASO graphics processor, which offers an array of display functionality and options. The ESP8266 WiFi module is pre-programmed with the AT command set firmware, enabling many WiFi capabilities right out of the box.
The 72.8x53.3x14.6mm 4Duino-24 also features a microSD connector, and headers in the Arduino layout, including 5V, 3.3V, GND and VIN power pins, 20 digital IO pins, of which 7 can be used PWM outputs and 12 pins have Analog input capabilities.
The Workshop4 IDE and its 3 different 4Duino based development environments lets users program the 4Duino using the Arduino programming language.
