Launchy: common questions

What microcontroller does the Launchy use?

The Launchy is built around the ESP32-C3-MINI-1-N4, from the ESP32 family.

How big is the Launchy PCB?

The Launchy measures 61.5 × 50.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Launchy?

33 components, from 18 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 Launchy design files?

From the sanko0112/Launchy repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the Launchy design in my own project?

Yes, under the terms of its MIT license, which sanko0112 chose for the repository.

Can I test firmware for the Launchy 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.
