Tao Te Ching RIGHT: common questions

What microcontroller does the Tao Te Ching RIGHT use?

The Tao Te Ching RIGHT is built around the XIAO-nRF52840-DIP, from the Nordic nRF family.

How big is the Tao Te Ching RIGHT PCB?

The Tao Te Ching RIGHT measures 138.1 × 89.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tao Te Ching RIGHT?

49 components, from 3 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 Tao Te Ching RIGHT design files?

From the sudo-apt-install-tap/TaoTeChing repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Tao Te Ching RIGHT design in my own project?

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

Can I test firmware for the Tao Te Ching RIGHT without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
