Cacao: common questions

What microcontroller does the Cacao use?

The Cacao is built around the RaspberryPi_Pico, from the RP2040/RP2350 family.

How big is the Cacao PCB?

The Cacao measures 350.6 × 97 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Cacao?

228 components, from 34 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 Cacao design files?

From the JustAGlitchFL/Cacao 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 Cacao design in my own project?

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

Can I test firmware for the Cacao without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
