ESP32-MySensors-Gateway: common questions

What microcontroller does the ESP32-MySensors-Gateway use?

The ESP32-MySensors-Gateway is built around the ESP-WROOM-32, from the ESP32 family.

How big is the ESP32-MySensors-Gateway PCB?

The ESP32-MySensors-Gateway measures 55 × 95 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-MySensors-Gateway?

47 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-MySensors-Gateway design files?

From the freynder/ESP32-MySensors-Gateway repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the ESP32-MySensors-Gateway design in my own project?

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

Can I test firmware for the ESP32-MySensors-Gateway 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.
