Skywatch: common questions

What microcontroller does the Skywatch use?

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

How big is the Skywatch PCB?

The Skywatch measures 233.7 × 91.5 mm, has 2 copper layers and is 1.2 mm thick.

How many components are on the Skywatch?

120 components, from 23 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 Skywatch design files?

From the ozkan/skywatch 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 Skywatch design in my own project?

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

Can I test firmware for the Skywatch 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.
