Jumper #
Description
J1
*
Output MOSFET drive pins.
J2 Full-bridge drive circuit (Drives 1 and 2): Place three shunts vertically on
these pins to create a full-bridge drive circuit incorporating Drives 1 and 2.
J3 Full-bridge drive circuit (Drives 3 and 4): Place three shunts vertically on
these pins to create a full-bridge drive circuit incorporating Drives 3 and
4.
J4
*
Temperature sensor, light sensor, potentiometers, 32.768 oscillator and
switches signal pins.
J5
*
Right-side signal pins of the 20-pin DIP socket (U2, pins 11-20).
J6
*
Left-side signal pins of the 20-pin DIP socket (U2, pins 1-10).
J7* Optical interrupter feedback signal pins.
J10
*
Right-side signal pins of the 40-pin DIP socket (U1, pins 21-40).
J13
*
Left-side signal pins of the 40-pin DIP socket (U1, pins 1-20).
J14 LED connect pins.
J15
*
Current sense feedback from the drive stage.
J16
*
Back EMF feedback signal pins.
JP2 Single-pin serial communication jumper (see Section 1.8.5 “Serial
Communication” for details).
JP8 Drive circuit voltage selection. See diagram on board.
* On these jumpers, the pins are connected in pairs horizontally. This allows
one pin to be used for jumping to/from the microcontroller (using a wire
jumper) and the other pin for probing the circuit with test equipment.
