Pcm5102a board: common questions

What microcontroller does the Pcm5102a board use?

The Pcm5102a board is built around the ESP32-S3-DEVKITC, from the ESP32 family.

How big is the Pcm5102a board?

The Pcm5102a board measures 100 × 50 mm, has 4 copper layers and is 1.6062 mm thick.

How many components are on the Pcm5102a board?

79 components, from 33 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 Pcm5102a board design files?

From the cbaurtx/RetroBox 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 Pcm5102a board design in my own project?

Yes, under the terms of its CERN-OHL-W-2.0 license, which cbaurtx chose for the repository.

Can I test firmware for the Pcm5102a board 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.
