Lora gateway: common questions

What microcontroller does the Lora gateway use?

The Lora gateway is built around the ATmega2560-16A, from the AVR/Arduino family.

How big is the Lora gateway PCB?

The Lora gateway measures 78.3 × 25.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Lora gateway?

23 components, from 13 distinct parts. The full bill of materials is listed on this page.

Where can I download the Lora gateway design files?

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

Can I use the Lora gateway design in my own project?

It is published under CC-BY-NC-4.0, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Lora gateway without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug AVR/Arduino firmware against it before you order a PCB.
