Gbczero: common questions

What microcontroller does the Gbczero use?

The Gbczero is built around the RASPBERRY_PI_ZERO_2_W, from the Raspberry Pi family.

How big is the Gbczero PCB?

The Gbczero measures 71.4 × 128 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Gbczero?

78 components, from 44 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 Gbczero design files?

From the hahhen/gbczero 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 Gbczero design in my own project?

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

Can I test firmware for the Gbczero without the hardware?

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