Esp32-lora multi gateway: common questions

What microcontroller does the Esp32-lora multi gateway use?

The Esp32-lora multi gateway is built around the ESP32-WROOM-32, from the ESP32 family.

How big is the Esp32-lora multi gateway PCB?

The Esp32-lora multi gateway measures 140 × 100 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-lora multi gateway?

81 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-lora multi gateway design files?

From the enriquewph/esp-map repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32-lora multi gateway design in my own project?
