Desktop light: common questions

What microcontroller does the Desktop light use?

The Desktop light is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Desktop light PCB?

The Desktop light measures 100 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Desktop light?

95 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Desktop light design files?

From the rmingon/desktop-light repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Desktop light design in my own project?

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

Can I test firmware for the Desktop light 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.
