Tas5805m: common questions

What microcontroller does the Tas5805m use?

The Tas5805m is built around the STM32F103C8Tx, from the STM32 family.

How big is the Tas5805m PCB?

The Tas5805m measures 90 × 90 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tas5805m?

104 components, from 52 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tas5805m design files?

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

Can I use the Tas5805m design in my own project?

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

Can I test firmware for the Tas5805m 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.
