Tiny touch auto route: common questions

What microcontroller does the Tiny touch auto route use?

The Tiny touch auto route is built around the STM32F072VBT6, from the STM32 family.

How big is the Tiny touch auto route PCB?

The Tiny touch auto route measures 100.3 × 76 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tiny touch auto route?

68 components, from 26 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tiny touch auto route design files?

From the c-keys/tiny-touch repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Tiny touch auto route design in my own project?

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

Can I test firmware for the Tiny touch auto route 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.
