Luma: common questions
What microcontroller does the Luma use?
The Luma is built around the C701342, from the ESP32 family.
How big is the Luma PCB?
The Luma measures 40 × 58 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Luma?
78 components, from 46 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 Luma design files?
From the notaroomba/luma 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 Luma design in my own project?
The repository has no license, so all rights stay with notaroomba. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Luma 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.
