About the RGB LED 1.4 PCB

RGB LED 1.4 is an open source AVR/Arduino PCB design by lachlanA, published on GitHub under the GPL-2.0 license. It is a board measuring 81.3 × 53.3 mm, with 39 components from 14 distinct parts.

Its main chip is the ARDUINO POWER, from the AVR/Arduino family. Other key parts include the TLC9450NT. By type, the board carries 16 LEDs, 9 jumpers, 4 resistors, 3 ICs, 3 switches and 3 capacitors.

From the project

Eagle SCH/LIB to KiCad SCH/LIB ULP conversion script

The following 5 ulp (eagle user script file) and one ulp include file, work together or stand alone to convert Eagle sch/pcb version 6.xx(7.xx-8.xx maybe?) file(s) and any version of Eagle lib(lbr) to KiCad sch/pcb and lib/mod* files.

The Programs will do Eagle multi sheet schematic to KiCad multi sheets. Global and local net labels for multi sheets. (This is a real nasty bit of hacking!) Multi part gates. Build KiCad PCB modules and sch libs from Eagle sch. Make project director to store all the converted files. And basic error checking. Eagle 6.xx(7.xx-8.xx?) PCB files can be directly…

RGB LED 1.4: common questions

What microcontroller does the RGB LED 1.4 use?

The RGB LED 1.4 is built around the ARDUINO POWER, from the AVR/Arduino family.

How big is the RGB LED 1.4 PCB?

The RGB LED 1.4 measures 81.3 × 53.3 mm and is 1.6 mm thick.

How many components are on the RGB LED 1.4?

39 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the RGB LED 1.4 design files?

From the lachlanA/eagle-to-kicad repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the RGB LED 1.4 design in my own project?

Yes, under the terms of its GPL-2.0 license, which lachlanA chose for the repository.

Can I test firmware for the RGB LED 1.4 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.
