Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the AMS1117-3.3. By type, the board carries 10 connectors, 9 capacitors, 3 ICs, 3 resistors and 2 switches.
From the project
YoRadio PCB
Hardware project of a printed circuit board (PCB) for YoRadio. The repository contains the complete KiCad project and ready-to-fabricate files (Gerbers + drill), as well as screenshots and board photos.
Status: stable v0.4 (fabrication files in the YRv0.4 directory and the YRv0.4.zip archive)
Note: Polish version available in README.pl.md
- Two-layer printed circuit board project for YoRadio. - KiCad files allow editing the schematic and PCB and generating new fabrication outputs. - The repository includes photos and screenshots of the project, as well as a Bill of Materials (BOM).

YR-PCB-v0.4: common questions
What microcontroller does the YR-PCB-v0.4 use?
The YR-PCB-v0.4 is built around the ESP32-S3-WROOM-1, from the ESP32 family.
How big is the YR-PCB-v0.4?
The YR-PCB-v0.4 measures 113.5 × 33 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the YR-PCB-v0.4?
27 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the YR-PCB-v0.4 design files?
From the PROTONMM/YR-PCB-v0.4 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the YR-PCB-v0.4 design in my own project?
Yes, under the terms of its GPL-3.0 license, which PROTONMM chose for the repository.
Can I test firmware for the YR-PCB-v0.4 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.
