BuhSat v0: common questions

What microcontroller does the BuhSat v0 use?

The BuhSat v0 is built around the Pico, from the RP2040/RP2350 family.

How big is the BuhSat v0 PCB?

The BuhSat v0 measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BuhSat v0?

32 components, from 20 distinct parts. The full bill of materials is listed on this page.

Where can I download the BuhSat v0 design files?

From the Sadteeto/BuhSat-v0 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the BuhSat v0 design in my own project?

Yes, under the terms of its MIT license, which Sadteeto chose for the repository.

Can I test firmware for the BuhSat v0 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.
