Tianyan: common questions

What microcontroller does the Tianyan use?

The Tianyan is built around the RaspberryPi_Pico_W, from the Raspberry Pi family.

How big is the Tianyan PCB?

The Tianyan measures 62.2 × 120 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tianyan?

8 components, from 7 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 Tianyan design files?

From the Innaf0/Tianyan 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 Tianyan design in my own project?

Yes, under the terms of its GPL-3.0 license, which Innaf0 chose for the repository.

Can I test firmware for the Tianyan without the hardware?

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