Tiny PIC boards for fast projects?

[mobbarley]

Hi all,

I'm sensing a one off project coming up and might need to produce ~30 small pic boards.Does anyone know of any really small and simple PIC boards on the market for this sort of quick project? I did a nights worth of googling and could find anything.

Ideally i'd like a small professional board with a 16F or 18F, oscillator, regulator, ICSP header and a tiny bit of proto area - but I need the board to be a small as possible. Surely these exist...

why not layout your own PCB and get it made up ? where are you located ?

Designing boards isn't a problem - the problem is that I don't want to have to send away for boards, wait and then build them when they come. A premade board would be ideal so that I can just pop on a couple of resistors and terminal blocks for my interface (about 4-5 IO pins), program and my tiny data converter is done.

Hi,

StartUSB for PIC
http://www.mikroe.com/eng/products/view/631/startusb-for-pic/

This was my first choice because I like its size and have used Mikroe's products before. However I don't need USB or bootloader (no big deal) and it unfortunately still requires a vreg, cap, and a few air wires to connect it up. Still - it is the best professional looking option so far.

Would my TAP-28 board fit your needs?  It supports most 28 pin PIC parts and has dedicated connectors for ICSP, UART I2C/SPI (each of these 6 pin connectors has power, ground and 4 data lines that can be used for the hardware function or for general purpose use), 2 3-pin connectors with power, ground and a PWM-capable port pin and 2 3-pin connectors with power, ground and an ADC/general purpose port pin.

There is no on-board prototype area but many of the lines on the 6-pin connectors have provision for a pullup resistor and the 3-pin connectors has provision for a pullup or pull-down resistor.  There's also provision for a row of parallel headers for a daughter board the connects to all the port pins.  Depending on how complex your add-ons are, it may be possible to solder the needed parts directly to the header locations or to use a small piece of perf board to add the parts.

For a quantity, I'll definitely give you an awesome price

I did find your board in my googling! Let me look into it tomorrow!

Thanks,

I have a some that host a 12f675, using onboard clock, the only thing on the board besides the pic is a FET, resistor and a few caps.  I have a .5" x .75" version and a .75" x 1" version.  Dimensions are approximate.  The pins for iscp are there, but get used if you hook anything up so don't plan on reprogramming.  I can send a jig with the boards, I use one of the boards to make the jig with some springy pins.

If you think it might work, I will put up some pictures.  I do realize that I am missing some of your specs, but you said you wanted really small and thought you may be able to be flexible to get a smaller board.

Have a great day!
