RoverDrive-Hardware: common questions

What microcontroller does the RoverDrive-Hardware use?

The RoverDrive-Hardware is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the RoverDrive-Hardware PCB?

The RoverDrive-Hardware measures 52.8 × 67 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RoverDrive-Hardware?

46 components, from 27 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 RoverDrive-Hardware design files?

From the eet-cheez/RoverDrive-Hardware 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 RoverDrive-Hardware design in my own project?

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

Can I test firmware for the RoverDrive-Hardware 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.
