Smdboard: common questions

What microcontroller does the Smdboard use?

The Smdboard is built around the STM32F091RxHx, from the STM32 family.

How big is the Smdboard PCB?

The Smdboard measures 50 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Smdboard?

164 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Smdboard design files?

From the adamgreig/smdboard repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Smdboard design in my own project?

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

Can I test firmware for the Smdboard 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.
