AWC Electronics - GPMPU40 PIC Prototyping Board
Shown with user-supplied components including an Atmel ATMega32 Processor
This versatile board provides the ultimate flexibility for microcontroller designers. A unique pattern allows you to fit virtually any 40, 32, 28, 24, 18, 16, or 8 pin processor into this PCB. The board provides connections to a breadboard, a 5V power supply, a crystal or resonator, a reset circuit, and a flexible RS232 subsystem. New: This board is now available with a 28 pin SSOP adapter perfect for many surface mount processors!
It is great to test and debug processor circuits on a breadboard. But it is tedious to have to build your basic circuit on a breadboard for each project. The GPMPU40 plugs directly into a standard solderless breadboard and provides access to all 40 pins right to the breadboard. It also provides a customizable connector for a programmer or other external connection. When you are ready to put your product in the field, you can solder an ordinary "prototype" PCB to the GPMPU40's breadboard connector.

The unique hole pattern used by the GPMPU40 allows you to connect the various subsystems to the CPU. Of course, you can also use the breadboard header to connect to any real-world device you like after your design is off the breadboard (see an example). Four mounting holes allow the GPMPU to install permanently, if desired. The high-quality double sided board has plated through holes, solder mask, and silk screen markings to make assembly simple. The included instructions show the schematic, parts list, and it also discusses many possible customizations you may wish to make. |

The board accepts virtually any 40, 32, 28, 24, 18, 16, or 8 pin processor with either .6" or .3" spacing. You can read the manual online. If you use a chip smaller than 40 pins, you can use the unused area for other ICs like EEPROMs, A/Ds, etc. For example, you could use a 24 pin Basic Stamp and still have room for 2 8 pin EEPROMs!
The board can be configured for a wide variety of chips including:
|
Any Microchip PIC in DIP packaging (18F254, 18F252, 16F877, 16F873, 16F628, 16F84, etc.) |

The RS232 system is flexible allowing you to connect the DB9 as a DTE or DCE device. You can also use jumpers on the board to select one auxiliary input and one output (that is, RTS and CTS, for CD and DTR).
If you are breadboarding or you just want a robust platform for your microprocessor projects, you want the GPMPU40!
The core components kit includes:
| MAX232 and associated capacitors | |
| DB9 connector | |
| Power supply components | |
| An IC socket | |
| Resistor | |
| Pin headers and jumper caps |
You need a processor and resonator (or crystal/capacitor) which will vary, of course, depending on your specific application (see our components page for a choice of PICs and low-cost ceramic resonators). The board will also accept an optional 2mm power connector and a three-terminal reset controller, for those processors that require it.
This is a kit, so you'll have a chance to customize it as you assemble it. All the parts are through hole and the PCB is silk screened and solder masked.
The GPMPU40 is available today. You can get the entire kit, or just the parts you want or need, including just the bare board.
