Zeen-AI-Plug: common questions

What microcontroller does the Zeen-AI-Plug use?

The Zeen-AI-Plug is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Zeen-AI-Plug PCB?

The Zeen-AI-Plug measures 105 × 58 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Zeen-AI-Plug?

71 components, from 35 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 Zeen-AI-Plug design files?

From the ampnics/Zeen-AI-Plug 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 Zeen-AI-Plug design in my own project?

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

Can I test firmware for the Zeen-AI-Plug 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.
