PICdevelopment board

The board was populated successfully and most of the functional features of the board have turned out to be successful. I am yet to test one of the two voltage comparators available on the board.

The main features of the board include:

  1. PIC16F877A platform
  2. L293D module ( Can drive 2 geared DC motors or 1 stepper motor)
  3. ULN 2003A module for stepper motors
  4. Voltage comparator circuit for LDR based sensor module
  5. Voltage comparator circuit for IR LED – photodiode based sensor modules
  6. Analog Inputs
  7. Seven Segment Display * 4nos
  8. RS232 port
  9. LED outputs to test the comparators/voltage sensors
  10. 8 LEDs to test the outputs of the individual pins of the controller
  11. Plug and play option — Can test it with simple connecting wires across any pin of the microcontroller
  12. Power supply pins to power other add-on boards

Looking foward for your comments!
