Cz badge hardware: common questions
What microcontroller does the Cz badge hardware use?
The Cz badge hardware is built around the ESP32-WROVER, from the ESP32 family.
How big is the Cz badge hardware PCB?
The Cz badge hardware measures 100 × 110 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Cz badge hardware?
161 components, from 51 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 Cz badge hardware design files?
From the hackzone/cz20-badge repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Cz badge hardware design in my own project?
The repository has no license, so all rights stay with hackzone. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Cz badge hardware 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.
