L293d motor driver

Features
The L293D is a popular motor driver IC that is usable from 6 to12V, at up to 1A total output current. By itself, the IC is somewhat diffcult to wire and use, but the Compact L293D Motor Driver makes it much more convenient to use.
Board Special Features
  • Four motor direction indicator LEDS
  • Schottky EMF-protection diodes
  • Socket pin connectors for easy logic interfacing
  • Enable pins are user accessible.

These boards are designed specifically for the electronics content


These boards are designed specifically for the electronics content in the Electricity and Electronics unit of Higher Physics.

Now well established in Scottish schools, these are the original JJM electronics circuit boards.  Many users have commented on the clarity and ease of use of these boards.
GRAMPIAN OP AMP

Op Amp circuits are built using bare resistors, giving a very flexible but low cost method of construction.  The use of 1% tolerance resistors gives experimental results in impressive agreement with theory.

  • 4mm terminals for external connections (voltmeter, signal generator etc.)
  • miniature turned pin sockets for mounting resistors etc.
  • built circuits closely match circuit diagram
  • two on board pots for generating dc input signals


Order Code: 01-001  Price: £15.95

12V REGULATOR


An add on regulator board generating a +/-12V (100mA) dual rail supply from any 12V ac supply (labpack).



  • Ideal power supply for op amp board
  • Several boards may be powered from one labpack
  • Full overload and short circuit protection
  • Power on and overload indicators
  • Fuse protection for the board itself

  • Order Code: 01-004  Price: £16.50

    WHEATSTONE BRIDGE


    Allows bridge circuits to be built using bare 1% tolerance resistors which mount in miniature sockets.

    As with the op amp, this gives results which closely match theory.

    Order Code: 01-005  Price: £8.55
