Coaster: common questions

What microcontroller does the Coaster use?

The Coaster is built around the C3013941, from the ESP32 family.

How big is the Coaster PCB?

The Coaster measures 120 × 120 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Coaster?

275 components, from 22 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 Coaster design files?

From the evansj/ESP32-LED 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 Coaster design in my own project?

Yes, under the terms of its GPL-3.0 license, which evansj chose for the repository.

Can I test firmware for the Coaster 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.
