Upsy desky: common questions

What microcontroller does the Upsy desky use?

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

How big is the Upsy desky PCB?

The Upsy desky measures 40.9 × 58 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Upsy desky?

44 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Upsy desky design files?

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

Can I use the Upsy desky design in my own project?

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

Can I test firmware for the Upsy desky 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.
