Deskbuddy: common questions

What microcontroller does the Deskbuddy use?

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

How many components are on the Deskbuddy?

44 components, from 28 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 Deskbuddy design files?

From the FECstudios/deskbuddy repository on GitHub, which has the schematic and the BOM; the links under Design files point to each one.

Can I use the Deskbuddy design in my own project?

Yes, under the terms of its Apache-2.0 license, which FECstudios chose for the repository.

Can I test firmware for the Deskbuddy 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.
