Project-Tachometer: common questions

What microcontroller does the Project-Tachometer use?

The Project-Tachometer is built around the STM32F103C8T6TR, from the STM32 family.

How big is the Project-Tachometer PCB?

The Project-Tachometer measures 50.3 × 50.2 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Project-Tachometer?

50 components, from 32 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 Project-Tachometer design files?

From the SrikarBharadwajR/Project-Tachometer 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 Project-Tachometer design in my own project?

Yes, under the terms of its GPL-3.0 license, which SrikarBharadwajR chose for the repository.

Can I test firmware for the Project-Tachometer 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.
