PIC test board

[MrDEB]

Here is the PIC test board or protype test board.
Has a spdt selector switch to select either the 40 pin or 18 pin socket with indicator LEDs
lots of daughter board connections and LCD headers (don't have to rewire everytime I want to run an LCD program (need to redo code for the 18F1320)
Got the idea from **broken link removed**
the board streamlines the rewiring of parts for a breadboard. Also frees up breadboard space.

Dear nice effort. But where is the schematic you used and backside picture of the board for the board readers to evaluate your efforts

 

[MrDEB]

Will post updated pics of schematic.
backside is not real pretty as it is all point to point hard wiring using wire wrap wire.

 

[MrDEB]

test board to date

here is a schematic of what I have so far. Thinking about etching a board to eliminate alot of "wire traffic" which adds to the confussion.

Dear MrDEB
Awaiting your etched board results and pcb layout

 

[Pommie]

Looking at that schematic, you seem to have an LED (D1) that tells you when it's off!

Mike.

 

[MrDEB]

D1 and D3 are both connected to the selector switch. When selected the LED comes on.
I have an updated schematic and then on to a pc board.

updated schematic

Here is a schematic in progress
Feel I shoulds add some port status LEDs? but which ones?? if any.
here is the link to the orginal idea of this board
Digital Electronics Forum • View topic - A 'throw-away" PIC board
any suggestions are welcome as well as connections not right.
I was contemplating using a plug in 9v battery holder instead of 9v battery leads. less likely to break off.

here is the START of PCboard

not real small 5x7"
has on board power supply.
This is for a two layer board with all grounds, Vccicsp, crystals on top layer (should make registration easier?
All ports on bottom layer.

 

[MrDEB]

bottom layer of pc board

this pcboard has yet to be doubled checked but there really isn't much to look at,
ALL the ports are connected using the bottom layer.
NOTE I changed a few headers.

 

[MrDEB]

updated test board schematics

added an LCD port to the 40 pin section, several logic buttons.
I have express pcb files if anyone interested.
This board should save lots of bread board repetitive circuits.
ANY addition suggestions welcome
