The KiCad project lives in the cubistmind/__pCennnBeist repository on GitHub; these links point at the commit this page was built from.

Gitcard final version: common questions

What microcontroller does the Gitcard final version use?

The Gitcard final version is built around the ESP32-H2-MINI-1, from the ESP32 family.

How big is the Gitcard final version PCB?

The Gitcard final version measures 57.5 × 85.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gitcard final version?

298 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Gitcard final version design files?

From the cubistmind/__pCennnBeist repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Gitcard final version design in my own project?

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

Can I test firmware for the Gitcard final version 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.
