AetherLink: common questions

What microcontroller does the AetherLink use?

The AetherLink is built around the ESP32-C3-WROOM-02U, from the ESP32 family.

How big is the AetherLink PCB?

The AetherLink measures 27 × 43 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the AetherLink?

37 components, from 21 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 AetherLink design files?

From the FBIopeningUPP/AetherLink 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 AetherLink design in my own project?

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

Can I test firmware for the AetherLink 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.
