Takt11800: common questions

What microcontroller does the Takt11800 use?

The Takt11800 is built around the STM32F072CBT6, from the STM32 family.

How big is the Takt11800 PCB?

The Takt11800 measures 391.2 × 166.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Takt11800?

276 components, from 46 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 Takt11800 design files?

From the vuckale/takt11800 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 Takt11800 design in my own project?

Yes, under the terms of its CERN-OHL-S-2.0 license, which vuckale chose for the repository.

Can I test firmware for the Takt11800 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.
