Karabas Go Mini: common questions
What microcontroller does the Karabas Go Mini use?
The Karabas Go Mini is built around the RP2040, from the RP2040/RP2350 family.
How big is the Karabas Go Mini PCB?
The Karabas Go Mini measures 70 × 69.8 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Karabas Go Mini?
205 components, from 65 distinct parts. The full bill of materials is listed on this page.
Where can I download the Karabas Go Mini design files?
From the andykarpov/karabas-mini-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Karabas Go Mini design in my own project?
It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.
Can I test firmware for the Karabas Go Mini 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.
