Tachi-Ninja: common questions

What microcontroller does the Tachi-Ninja use?

The Tachi-Ninja is built around the STM32F072C8Tx, from the STM32 family.

How big is the Tachi-Ninja PCB?

The Tachi-Ninja measures 308.5 × 129 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tachi-Ninja?

201 components, from 73 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 Tachi-Ninja design files?

From the CreatorPoints/Tachi-Ninja 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 Tachi-Ninja design in my own project?

Yes, under the terms of its MIT license, which CreatorPoints chose for the repository.

Can I test firmware for the Tachi-Ninja 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.
