Tas5805m mux board: common questions
What microcontroller does the Tas5805m mux board use?
The Tas5805m mux board is built around the ESP32-S3-DEVKITC, from the ESP32 family.
How big is the Tas5805m mux board?
The Tas5805m mux board measures 99.1 × 99.1 mm, has 4 copper layers and is 1.6062 mm thick.
How many components are on the Tas5805m mux board?
96 components, from 50 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 Tas5805m mux 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 Tas5805m mux 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 Tas5805m mux 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.
