A collection of circuit designs for various MCUs, not just Raspberry Pis relating to Model Railroading
This is a collection of Model Railroad open hardware and open source projects, using LCC, OpenMRN, and OpenMRN-lite, for the following MCUs and SBCs:
Raspberry Pi, generally as HATs for the "B" flavors (RPi2B, RPi3B and RPi4B). (Directories with "HAT" at the end are for these boards.)
Beagle boards, including capes for BeagleBone Black and baseboards for PocketBeagles. (Directories with "CAPE" at the end are for BeagleBone Blacks, directories starting with "BBB" are also boards for the BeagleBone Black, directories starting with "PB" or "PocketBeagle" are for the PocketBeagles - these…

LPC176x MultiFunction: common questions
What microcontroller does the LPC176x MultiFunction use?
The LPC176x MultiFunction is built around the LPC1768FBD100K, from the NXP family.
How big is the LPC176x MultiFunction PCB?
The LPC176x MultiFunction measures 156.2 × 168.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the LPC176x MultiFunction?
223 components, from 70 distinct parts. The full bill of materials is listed on this page.
Where can I download the LPC176x MultiFunction design files?
From the RobertPHeller/RPi-RRCircuits repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the LPC176x MultiFunction design in my own project?
Yes, under the terms of its CC-BY-4.0 license, which RobertPHeller chose for the repository.
Can I test firmware for the LPC176x MultiFunction without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
