Piyopiyo: common questions

What microcontroller does the Piyopiyo use?

The Piyopiyo is built around the XIAO-ESP32S3, from the ESP32 family.

How big is the Piyopiyo PCB?

The Piyopiyo measures 100 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Piyopiyo?

49 components, from 30 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 Piyopiyo design files?

From the piyopiyoex/piyopiyo-pcb 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 Piyopiyo design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which piyopiyoex chose for the repository.

Can I test firmware for the Piyopiyo without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.

Earlier revisions in the repo: piyopiyo-pcb-v1.9, piyopiyo-pcb-v1.7
