Grid trunks attempt: common questions

What microcontroller does the Grid trunks attempt use?

The Grid trunks attempt is built around the ESP32-S31NRV16, from the ESP32 family.

How big is the Grid trunks attempt PCB?

The Grid trunks attempt measures 44 × 34 mm, has 2 copper layers and is 0.8 mm thick.

How many components are on the Grid trunks attempt?

23 components, from 14 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 Grid trunks attempt design files?

From the 0x616c6f6e/esp32s31-mp3 repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Grid trunks attempt 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 Grid trunks attempt 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.
