Product Details

Select a section:


An “MCU” section containing

  • An 80-pin LQFP socket accepting either the MC9S08QE128 or the MCF51QE128 microcontroller
  • A crystal oscillator, a provision for a clock module, a provision for a connector for providing an external clock source, together with jumpers to select the clock source
  • A BDM connector for in-circuit debugging/programming with an external instrument
  • A female header connector with all of the MCU signals

An “I/O” section containing

  • A Reset push button
  • Four additional push button
  • One potentiometer
  • Eight dip-switches
  • A piezoelectric buzzer
  • A light sensor
  • A temperature sensor
  • Ten user LEDs
  • A circuitry for driving and external LCD
  • A series of jumpers to connect/disconnect the above controls to/from the microcontroller


  • An “RS-232” section containing two RS-232 connectors together with a jumper to enable the RS-232 communication
  • A “SERIAL SETTINGS” section containing jumpers to select communication options

A power supply section containing

  • A 12 VDC barrel input connector (2.1 mm)
  • A four-way micro terminal block for providing specific power supplies and voltage references to the microcontroller
  • A jumper to select the power supply source (USB bus or barrel connector)
  • A power on/off switch


  • Section (with the main circuitry mounted on the back of the board) which allows the host PC to communicate with the microcontroller through a standard USB interface. Jumpers are present to configure this module. Thanks to the microDART in-circuit debugging firmware, BDM commands are sent to the target microcontroller through the USB bus. Additionally, a virtual COM port is automatically available over the same USB connection. This virtual COM port can be used by standard terminal programs, like HyperTerminal, to send/receive serial characters to/from the target microcontroller
