PIC16F628a development board

thingiverse

This is a very simple development board for the PIC16F628a (or any other 18 pin pic with the the ICSP on the same pins). It has an ICSP pin header for use with a PICKIT2 (or anything that is compatible with it) and the three rows of pins: one for the microcontroller pins, one connected to the 5v and one to the gnd, arranged in a way that makes it easy to connect a servo or any other module directly to the board, without the need for a breadboard. It has a built-in led on the RB5 pin, a reset button, a DC jack, AMS1117a regulator and a power led. There are pads for an external crystal oscillator and 22pf capacitors. The ingredient list: - One PIC16F628a and a 18 pin DIP socket - Two 3mm leds. - Two 10k resistors - Two 1k resistors - Two electrolytic capacitors of any value above 4.7uf and of any voltage rating above 16v - One omron-like tactile switch - One AMS1117-5v (it can be a lower voltage one like the 3v3 version, but you'll need to change the 1k resistors to make the LEDs bright enough on 3v3). - 3 x 16 male or female pin headers - 1 x 5 or 6 pin male or female pin header (for the ICSP). - One 4 to 20 mhz HC49 crystal oscillator and two 22 pf capacitors. Not necessary if you're going to use the internal oscillator. Etch the board, solder everything in. Keep the component leads to make the jumpers. Download your program to the board with a PICKIT2 or compatible. That's about it!
