SDLH EV: common questions

What microcontroller does the SDLH EV use?

The SDLH EV is built around the ESP32-S3-WROOM-1U-N4R2, from the ESP32 family.

How many components are on the SDLH EV?

82 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the SDLH EV design files?

From the ManchesterStingerMotorsports/SDLH_EV repository on GitHub, which has the schematic; the links under Design files point to each one.

Can I use the SDLH EV design in my own project?

The repository has no license, so all rights stay with ManchesterStingerMotorsports. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the SDLH EV 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.
