Overview
Pic dev board is an open-source printed circuit board by bablokb, from the bablokb/pcb-pic-devboard repository on GitHub, published under the CC-BY-SA-4.0 licence. It is a 2-layer board of 100 × 100 mm with 80 parts on 97 nets, routed with 666 tracks and 29 vias.
It is built around the 74HC595. Its parts include 23 connectors, 22 diodes, 17 resistors, 5 ICs and 1 capacitor. It belongs with the microcontroller boards boards and the PIC boards of this library.

Readme.mdDevelopment board for PIC12/PIC16 microcontrollers
This repository contains the design-files (Kicad) for three PIC12/PIC16 development boards.
PIC-Dev-Board
This is a full sized dev-board, see directory pic-dev-board.kicad:
It supports:
- a PIC12 or a 20-pin PIC16
- configurable pullups or LEDs on GP0-GP5
- two shift-registers with LEDs to output 8-16 bits using two GPs (see project pic-sn74hc595)
- a LCD1602 attached to the first shift-register (see project pic-hd44780_lcd)
- ICSP programming
- all pins broken out to connectors (TRISB/TRISC only available for PIC16)
- a large prototyping-area
PIC12-Dev-PCB
This is a small dev-board for PIC12 MCUs designed for plugging into a
breadboard, see directory pic12-dev-pcb:
It supports:
- PIC12 in SO-8 package
- ICSP programming
- connector for an external SN74HC595-pcb (see project pic-sn74hc595
- also usable as I2C-connector
- power-supply using a small micro-USB-connector breakout
- connector for power-out (should align with the power-rails of the breadboard)
- a small prototyping area
- a small switch (optional)
- two LEDs (optional)
Minimal Stripboard Version
In the directory pic12-dev-stripboard.kicad you find the schema and layout for
a minimal stripboard version:
This is a simple solution for plugging a PIC12 into a breadboard.
This version is not meant for ICSP (in-circuit serial programming), since it does not have any components to guard the rest of the circuit during programming.
