IndegoRover: common questions

What microcontroller does the IndegoRover use?

The IndegoRover is built around the ESP32-S3-WROOM-2 (-1), from the ESP32 family.

How big is the IndegoRover PCB?

The IndegoRover measures 172 × 230 mm, has 2 copper layers and is 1.579 mm thick.

How many components are on the IndegoRover?

28 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the IndegoRover design files?

From the MS71/IndegoRover repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the IndegoRover design in my own project?

The repository has no license, so all rights stay with MS71. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the IndegoRover 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.
