Tuner: common questions

What microcontroller does the Tuner use?

The Tuner is built around the C2891839, from the STM32 family.

How big is the Tuner PCB?

The Tuner measures 48.3 × 40.8 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Tuner?

46 components, from 37 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 Tuner design files?

From the WilliamLim781/PCB_practice 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 Tuner design in my own project?

The repository has no license, so all rights stay with WilliamLim781. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Tuner 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.
