My collection of home-built PIC experimenter breadboard modules.

Here are some of my home-built breadboard modules and a PIC programmer board kit I bought.

I built most of my modules on sections of Radio Shack 276-150 multipurpose pc board cutting the board to size as needed. I also made a couple of breadboard modules by laying them out in Eagle Layout and making printed circuit boards, but It is a bit more time consuming.

I also soldered header pins to the module boards or to wires attached to the boards so they can be plugged directly into a breadboard.

Power Module

I use 9 volt dc power adapters to power my 5 volt regulated breadboard modules. The modules have an on/off switch with an indicator led on the output.

8 LED PIC chip breadboard module.

LED Module

The led module has an 8 pin header to monitor the output ports of a PIC chip and two ground pins to connect to the negative power strip on a breadboard.

Push Button Switch Module

The push button switch module has eight momentary contact switches with pull up resistors. When a button is pushed it pull the corresponding header pin to ground. If you reverse the power pin polarity the resistors will pull down and output will switch high.

8 SPST switch PIC chip breadboard module.

Eight SPST Switch Module

The switch module uses an eight SPST rocker switch DIP package. When a switch is in the off position a 10K resistor pulls it's corresponding breadboard header pin to ground. When the switch is moved to the on position the header pin is switched to 5 volts.

If you reverse the polarity of the red and black module leads the resistors will pull the breadboard header pins up to 5 volts with the switches in the off position and the output will switched low when the switches are in the on position.

Home-built dual serial port module for computer serial port to PIC chip communications.

Dual Serial Port Module

The serial port module has DB9 connectors to connect to a computer and pins to plug into a breadboard to interface with a PIC chip. It also has a momentary button to use as a master clear reset when the blue lead is connected to the MCLR pin of the PIC chip. The heart of the module is the MAX232CPE ic.
