ESP32PoEAlarm: common questions

What microcontroller does the ESP32PoEAlarm use?

The ESP32PoEAlarm is built around the ESP32-POE, from the ESP32 family.

How big is the ESP32PoEAlarm PCB?

The ESP32PoEAlarm measures 186.8 × 87.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32PoEAlarm?

31 components, from 8 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32PoEAlarm design files?

From the AlexTischer/ESP32PoEAlarm repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32PoEAlarm design in my own project?

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

Can I test firmware for the ESP32PoEAlarm 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.
