Tiny tapeout: common questions

What microcontroller does the Tiny tapeout use?

The Tiny tapeout is built around the SC0914(13), from the RP2040/RP2350 family.

How big is the Tiny tapeout PCB?

The Tiny tapeout measures 104.5 × 81 mm, has 4 copper layers and is 1.56252 mm thick.

How many components are on the Tiny tapeout?

131 components, from 39 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tiny tapeout design files?

From the nickradfc/tiny_tapeout repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Tiny tapeout design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Tiny tapeout without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
