Rgb butterfly: common questions

What microcontroller does the Rgb butterfly use?

The Rgb butterfly is built around the ESP32-WROOM-32E, from the ESP32 family.

How big is the Rgb butterfly PCB?

The Rgb butterfly measures 21 × 81.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Rgb butterfly?

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

Where can I download the Rgb butterfly design files?

From the bitsandpixels-io/rgb-butterfly repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Rgb butterfly design in my own project?

Yes, under the terms of its MIT license, which bitsandpixels-io chose for the repository.

Can I test firmware for the Rgb butterfly without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
