Add on Cerveza: common questions
What microcontroller does the Add on Cerveza use?
The Add on Cerveza is built around the CH32V003F4U6, from the RISC-V family.
How big is the Add on Cerveza PCB?
The Add on Cerveza measures 41.6 × 49.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Add on Cerveza?
17 components, from 12 distinct parts. The full bill of materials is listed on this page.
Where can I download the Add on Cerveza design files?
From the ElectronicCats/Badge_Tropicon-2026 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Add on Cerveza design in my own project?
The repository has no license, so all rights stay with ElectronicCats. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Add on Cerveza without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RISC-V firmware against it before you order a PCB.
