Desk buddy: common questions

What microcontroller does the Desk buddy use?

The Desk buddy is built around the XIAO-ESP32-C3-SMD, from the ESP32 family.

How big is the Desk buddy PCB?

The Desk buddy measures 78.7 × 72.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Desk buddy?

14 components, from 8 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 Desk buddy design files?

From the aryanscodingden/desk-buddy 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 Desk buddy design in my own project?

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

Can I test firmware for the Desk buddy 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.
