Uni60 Solder: common questions

What microcontroller does the Uni60 Solder use?

The Uni60 Solder is built around the STM32F072CBTX, from the STM32 family.

How big is the Uni60 Solder PCB?

The Uni60 Solder measures 284.7 × 94.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Uni60 Solder?

176 components, from 18 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 Uni60 Solder design files?

From the ShentoBento/Universal_PCBs 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 Uni60 Solder design in my own project?

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

Can I test firmware for the Uni60 Solder without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
