Uncut Gem bkup: common questions

What microcontroller does the Uncut Gem bkup use?

The Uncut Gem bkup is built around the DOIT-ESP32-DEVKIT-V2-30pin, from the ESP32 family.

How big is the Uncut Gem bkup PCB?

The Uncut Gem bkup measures 82.1 × 82.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Uncut Gem bkup?

78 components, from 40 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 Uncut Gem bkup design files?

From the QuantumVillage/UncutGem repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Uncut Gem bkup design in my own project?

Yes, under the terms of its AGPL-3.0 license, which QuantumVillage chose for the repository.

Can I test firmware for the Uncut Gem bkup 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.
