Dash: common questions

What microcontroller does the Dash use?

The Dash is built around the ESP32-S3-WROOM-1-N8R8, from the ESP32 family.

How big is the Dash PCB?

The Dash measures 130 × 81 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Dash?

105 components, from 48 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 Dash design files?

From the sundevilmotorsports/pcb-dev 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 Dash design in my own project?

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

Can I test firmware for the Dash 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.
