T20 pmod: common questions

What microcontroller does the T20 pmod use?

The T20 pmod is built around the SY8113BADC, from the RP2040/RP2350 family.

How big is the T20 pmod PCB?

The T20 pmod measures 53.6 × 71.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the T20 pmod?

15 components, from 12 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 T20 pmod design files?

From the MiSTle-Dev/Boards 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 T20 pmod design in my own project?

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

Can I test firmware for the T20 pmod 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.
