A1 - Analogue Board: common questions

What microcontroller does the A1 - Analogue Board use?

The A1 - Analogue Board is built around the STM32F303C6Tx, from the STM32 family.

How big is the A1 - Analogue Board?

The A1 - Analogue Board measures 309.1 × 225.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the A1 - Analogue Board?

273 components, from 66 distinct parts. The full bill of materials is listed on this page.

Where can I download the A1 - Analogue Board design files?

From the DumberThanUsual/DSMU repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the A1 - Analogue Board design in my own project?

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

Can I test firmware for the A1 - Analogue Board 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.
