Ornament: common questions
What microcontroller does the Ornament use?
The Ornament is built around the ESP32-WROOM-32, from the ESP32 family.
How big is the Ornament PCB?
The Ornament measures 55 × 96 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Ornament?
27 components, from 18 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 Ornament design files?
From the Matir/hacks repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Ornament design in my own project?
Yes, under the terms of its BSD-2-Clause license, which Matir chose for the repository.
Can I test firmware for the Ornament 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.
