A quantum leap in the world of computer-controlled fischertechnik models. The kit includes a 16-bit microcontroller, USB and serial interfaces, as well as 128 kByte of flash memory for downloading 2 different programs which are retained even if the power supply is disconnected. Four 9V/250mA (max. 1A) motor outputs now with variable speed control, 8 digital inputs, 2 analog inputs for resistances from 0- 5kO, 2 analog inputs for voltages from 0-10V and 2 inputs for digital distance sensors. One connection each for ROBO I/O Extension expansion module and ROBO RF Data Link radio interface, as well as an interface to infrared transmitter from the IR Control Set. Additional 26-pole male connector strip - to which all inputs and outputs are brought out - for convenient connection of finished models through a single 26-pole connector. Additional 9VDC power supply required (not included).
