A full-featured, multi-peripheral development and trainer board for the PIC18F microcontroller family — combining an on-board USB programmer, dual power input, and eleven plug-in peripheral modules (LEDs, keypad, LCD, UART, EEPROM, stepper driver, relays, and more) on a single 4-

A full-featured, multi-peripheral development and trainer board for the PIC18F microcontroller family — combining an on-board USB programmer, dual power input, and eleven plug-in peripheral modules (LEDs, keypad, LCD, UART, EEPROM, stepper driver, relays, and more) on a single 4-layer PCB, designed in KiCad.

Purpose This repository contains the full KiCad design (schematic, PCB layout, and fabrication outputs) for a PIC18F trainer/development board. It's built around a socketed PIC18F4331-IP target MCU with its own onboard USB-based ICSP programmer (PIC18F2550-ISO), and breaks out every port…

PIC DEV BOARD: common questions

What microcontroller does the PIC DEV BOARD use?

The PIC DEV BOARD is built around the 8051, from the PIC family.

How big is the PIC DEV BOARD?

The PIC DEV BOARD measures 140.7 × 128.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the PIC DEV BOARD?

102 components, from 51 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the PIC DEV BOARD design files?

From the anshukumar146/GitHub repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the PIC DEV BOARD design in my own project?

The repository has no license, so all rights stay with anshukumar146. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the PIC DEV BOARD without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
