Spark: common questions

What microcontroller does the Spark use?

The Spark is built around the RP2350A, from the RP2040/RP2350 family.

How big is the Spark PCB?

The Spark measures 82 × 55 mm, has 4 copper layers and is 1.5592 mm thick.

How many components are on the Spark?

196 components, from 57 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 Spark design files?

From the ratmuds/spark 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 Spark design in my own project?

The repository has no license, so all rights stay with ratmuds. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Spark 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.
