About the RC Light System PCB

RC Light System is an open source AVR/Arduino PCB design by tebl, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 36.2 × 41.3 mm, with 25 components from 21 distinct parts.

Its main chip is the Arduino Pro Micro, from the AVR/Arduino family. By type, the board carries 12 connectors, 6 resistors, 3 test points, 2 jumpers, 1 module and 1 diode.

From the project

Various projects on the road to creating a more interesting system for lights on RC cars. It won't be small, but at least I'll have fun making it.

Yeah! Turns out that doing exactly that, requires understanding a lot more than simply plugging an LED into a breadboard and turning it on or off - there's logic levels, reading a PWM signal and then figuring out how to design your own PCBs. So I eventually put my parts in the infamous "someday" pile. A decade later, I've learned a few things and it was time to take something off that pile and try again!

RC Light System: common questions

What microcontroller does the RC Light System use?

The RC Light System is built around the Arduino Pro Micro, from the AVR/Arduino family.

How big is the RC Light System PCB?

The RC Light System measures 36.2 × 41.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RC Light System?

25 components, from 21 distinct parts. The full bill of materials is listed on this page.

Where can I download the RC Light System design files?

From the tebl/RC-Light-System repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the RC Light System design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which tebl chose for the repository.

Can I test firmware for the RC Light System without the hardware?

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