RGB LED TOY: common questions

What microcontroller does the RGB LED TOY use?

The RGB LED TOY is built around the ATMEGA328-A, from the AVR/Arduino family.

How big is the RGB LED TOY PCB?

The RGB LED TOY measures 43.4 × 43.4 mm and is 1.6002 mm thick.

How many components are on the RGB LED TOY?

33 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the RGB LED TOY design files?

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

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

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

Can I test firmware for the RGB LED TOY 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.
