Soldermander: common questions

What microcontroller does the Soldermander use?

The Soldermander is built around the C1020268, from the NXP family.

How big is the Soldermander PCB?

The Soldermander measures 60 × 60 mm, has 6 copper layers and is 1.6 mm thick.

How many components are on the Soldermander?

161 components, from 54 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 Soldermander design files?

From the polygnomial/adcs 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 Soldermander design in my own project?

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

Can I test firmware for the Soldermander without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug NXP firmware against it before you order a PCB.
