Chippu has now upgraded its hardware, and is now much smarter. The Atmega32 is replaced by a more powerful and feature rich Atmega128 based Wiring Board. It has 53 I/O pins, 8 analog inputs, 2 hardware serial ports, 6 PWM (analog outputs), SPI, TWI, 8 external interrupts pins. Also it can drive a maximum of 24 servo motors. Quite impressive. A motor control board based on L293D was also added. Here are a few shots.
