* Based on the ATmega328p microcontroller @ 16 MHz (the heart of the Arduino Uno DIP model) * Size:  5cm X 2.5cm. 
* Plugs into a breadboard with the help of 0.1" (2.54mm) male headers or you can solder female headers.   * Arduino standard digital, analog, and special purpose pins exposed.  * Digital I/O Pins: 14 (of which 6 provide PWM output) - Analog Input Pins: 6  * 2 X LED: one for power and another for pin 13.   

* Reset button.
* 2 X 3-pin 0.1" (2.54mm) headers (5V) for small servos.  * 2 X 2-pin 0.1" (2.54mm) header for brushed DC motors.  * 6-pin 0.1" (2.54mm) ICSP male header. 
* 6-pin 0.1" (2.54mm) male header to accommodate FTDI USB programmer.  * Flash Memory: 32 KB of which 0.5 KB used by bootloader  * SRAM: 2 KB
* EEPROM: 1 KB   
* The GOduino III can be programmed with the Arduino IDE via an FTDI USB programmer * It can also be programmed via the ICSP header using programmers such as AVR-ISP,...
