The KiCad project lives in the rhine59/ESP32-EFIS repository on GitHub; these links point at the commit this page was built from.

ESP32-EFIS: common questions

What microcontroller does the ESP32-EFIS use?

The ESP32-EFIS is built around the ESP32-S3-WROOM-1-N16R2, from the ESP32 family.

How big is the ESP32-EFIS PCB?

The ESP32-EFIS measures 68 × 68 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32-EFIS?

25 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-EFIS design files?

From the rhine59/ESP32-EFIS repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32-EFIS design in my own project?

The repository has no license, so all rights stay with rhine59. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP32-EFIS 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.
