Esp32 mine: common questions

What microcontroller does the Esp32 mine use?

The Esp32 mine is built around the ESP32-S3, from the ESP32 family.

How big is the Esp32 mine PCB?

The Esp32 mine measures 36.1 × 68.9 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32 mine?

73 components, from 37 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 Esp32 mine design files?

From the mohamed-bekheet/PassPress 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 Esp32 mine design in my own project?

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

Can I test firmware for the Esp32 mine 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.
