Tt123-demo: common questions

What microcontroller does the Tt123-demo use?

The Tt123-demo is built around the Pico, from the RP2040/RP2350 family.

How big is the Tt123-demo PCB?

The Tt123-demo measures 104.5 × 81 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tt123-demo?

89 components, from 32 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tt123-demo design files?

From the TinyTapeout/tt123-demo-pcb repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tt123-demo design in my own project?
