Special thanks to icon-oclast for asking these great questions.

The 4 positions are for each line of the SPI connection between the pi pico and pi zero. This allows cutting the connections between pi pico and pi zero without cutting the power connections. I initially designed it for the (paranoid) scenario where I can't kill the pi zero, but doesn't want it to do…

CyberKeeb2040: common questions

What microcontroller does the CyberKeeb2040 use?

The CyberKeeb2040 is built around the Pico, from the RP2040/RP2350 family.

How big is the CyberKeeb2040 PCB?

The CyberKeeb2040 measures 308.8 × 130.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the CyberKeeb2040?

163 components, from 77 distinct parts. The full bill of materials is listed on this page.

Where can I download the CyberKeeb2040 design files?

From the zli117/CyberKeeb2040 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the CyberKeeb2040 design in my own project?
