Introduction: Pic 12f675 Mini Protoboard

Since I have a lot of ideas about different usages of microcontrollers it always happens I have to build basic microcontroller setup (microcontroller with oscilator).
Finaly I decided to make a small (or should I say mini) protoboard for PIC 12f675 (which I wanted to use for a small project). You can see the result on the picture.

Step 1: The Solder Side of the PCB

is here.

Step 2: The Component Side

is here.

Step 3: Elements Placing.

Elements are placed like that.

Step 4: This Is It.

If you'll only be using internal RC oscillator, you can omit the oscillator part (and jumpers).

actually what is this ??? pic programmer device or pic interfacing device???

As far as I can see, the main benefit of this board is the integration of the chip with a programming header which, depending on your programmer, could be beneficial. Certainly this would potentially make a nice PICkit-compatible PIC12F675 "package".

For the vast majority of prototyping applications featuring these devices the PIC12F675's factory-calibrated internal oscillator (INTOSC, see section 9.2.5 of datasheet DS41190C) is adequate and frees up an additional 2 I/Os. If you do use an external crystal you should aim to keep its load capacitors very close to the crystal package pins, to limit inductance, and the crystal itself close to the XTAL pins of the device.

Decoupling and PSU reservoir capacitors are a wise addition (certainly at the production stage of development) but hardly critical for breadboarding given the parasitic capacitance and the (likely) quality of bench power supply.

Your PCB layout is neat and tidy, although the spacing from the track to pin 5 of the PIC is unnecessarily close.

I was getting tired of constantly doing that (putting 3 components directly in the breadboard) - so I made one big component :)

So try the 12F609/615/617 chips. Trimmed onboard oscillator, no crystal required. :)

i just wanted to no what components wher used in this project

Probably a 10uf cap, a .1uf cap, an 8MHz crystal, some jumpers, and a programming header

Will that also work with a 12f629? I'm new to PIC chips, so I apologise if the question sounds a bit stupid...thanks in advance & well done by the way

Since I stopped doing electronics for a while - I have no idea. Hopefully somebody will be able to answer that.

Stopped doing electronics??!!? Why you did so? =( =0

Huh. So many projects and so little time.
But I'm slowly getting back to it (at least in my dreams :) ).
Have few ideas bouncing around:

nixie clock with DCF77
radioactivity detector
and some more (will add when they're done :) ).
