Aether: common questions
What microcontroller does the Aether use?
The Aether is built around the ESP32-S3-MINI-1U, from the ESP32 family.
How big is the Aether PCB?
The Aether measures 100 × 60 mm, has 6 copper layers and is 1.6 mm thick.
How many components are on the Aether?
167 components, from 67 distinct parts. The full bill of materials is listed on this page.
Where can I download the Aether design files?
From the nasheed-x/aether repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Aether design in my own project?
The repository has no license, so all rights stay with nasheed-x. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Aether 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.
