Iw-8-controller: common questions

What microcontroller does the Iw-8-controller use?

The Iw-8-controller is built around the Pico, from the RP2040/RP2350 family.

How big is the Iw-8-controller PCB?

The Iw-8-controller measures 167.3 × 103 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iw-8-controller?

198 components, from 44 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 Iw-8-controller design files?

From the mekatrol/electronics 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 Iw-8-controller design in my own project?

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

Can I test firmware for the Iw-8-controller 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.
