Pcb: common questions

What microcontroller does the Pcb use?

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

How big is the Pcb?

The Pcb measures 228.6 × 81 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Pcb?

89 components, from 17 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 Pcb design files?

From the sky2park/ostinato 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 Pcb design in my own project?

Yes, under the terms of its GPL-3.0 license, which sky2park chose for the repository.

Can I test firmware for the Pcb 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.
