PassPress: common questions

What microcontroller does the PassPress use?

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

How big is the PassPress PCB?

The PassPress measures 45.4 × 21.8 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the PassPress?

57 components, from 32 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 PassPress 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 PassPress 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 PassPress 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.
