RGB LED controller: common questions

What microcontroller does the RGB LED controller use?

The RGB LED controller is built around the ATTINY814-SS, from the AVR/Arduino family.

How big is the RGB LED controller PCB?

The RGB LED controller measures 35.5 × 15 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RGB LED controller?

16 components, from 9 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 RGB LED controller design files?

From the 42CrMo4/RGB_LED_controller repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the RGB LED controller design in my own project?

The repository has no license, so all rights stay with 42CrMo4. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RGB LED controller 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.
