Sure why wouldn't it be ? Just pick the pic you want bring out the ICSP pins to preogram and put some leds on PORTB 8 would be nice and a pot on AN0. That would make a nice starter board.
Plus bring the IO out to a header use 560 ohm on the leds that way you could still use PORTB with a LCD from the header.
Here is mine:
The thing is wired up "rats nest" style on the underside of the board.
The backplate is connected to the 0v supply lines to provide the basis of a ground plane.
mine is quite tedious to build........
behind the board is covered with plastic glass which prevent the connections from been altered. Ive used it for 2years and it still works fine
Not recognizing the device is an error I had with PK3 and the 12F683. The conditions which cause it to occur are apparently quite sporadic and not well defined. The solution is simple, set the PK3 voltage at 4.75 instead of 5.0 (I have not read of any problems with 3.3 V). After making that change, the problem disappeared. This was addressed on the Microchip forum.
It may not solve this problem, but it is worth a try.
