The ProPrj esp32s31-mp4 2026-09-22 measures 46 × 76 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the ProPrj esp32s31-mp4 2026-09-22?
135 components, from 57 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 ProPrj esp32s31-mp4 2026-09-22 design files?
From the 0x616c6f6e/esp32s31-mp3 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 ProPrj esp32s31-mp4 2026-09-22 design in my own project?
The repository has no license, so all rights stay with 0x616c6f6e. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ProPrj esp32s31-mp4 2026-09-22 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.
