Main board: common questions

What microcontroller does the Main board use?

The Main board is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Main board?

The Main board measures 84 × 114 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main board?

104 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Main board design files?

From the elkel53930/robosweep_twilight repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Main board design in my own project?

Yes, under the terms of its MIT license, which elkel53930 chose for the repository.

Can I test firmware for the Main board 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.
