PassPress CH32: common questions

What microcontroller does the PassPress CH32 use?

The PassPress CH32 is built around the W25Q128JVS, from the WCH CH32/CH55x family.

How big is the PassPress CH32 PCB?

The PassPress CH32 measures 44.1 × 19.1 mm, has 4 copper layers and is 0.8 mm thick.

How many components are on the PassPress CH32?

33 components, from 26 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 CH32 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 CH32 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 CH32 without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug WCH CH32/CH55x firmware against it before you order a PCB.
