LoRa Gateway project =====================

1. Core library: libloragw ---------------------------

This directory contains the sources of the library to build a gateway based on a Semtech LoRa multi-channel RF receiver (a.k.a. concentrator). Once compiled all the code is contained in the libloragw.a file that will be statically linked (ie. integrated in the final executable).

Esp32 lora gateway: common questions

What microcontroller does the Esp32 lora gateway use?

The Esp32 lora gateway is built around the DevkitC, from the ESP32 family.

How big is the Esp32 lora gateway PCB?

The Esp32 lora gateway measures 177.8 × 111.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32 lora gateway?

70 components, from 33 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32 lora gateway design files?

From the Kiogora/esp32_lora_gateway repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

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

Yes, under the terms of its MIT license, which Kiogora chose for the repository.

Can I test firmware for the Esp32 lora 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.
