## What it is
A reference implementation of a LoRaWAN end-device (node) stack written in C, with example projects for various MCU platforms. It implements LoRaWAN L2 1.0.4/1.1.0 specifications for Class A/B/C devices and is now in maintenance mode in favor of LoRa Basics Modem.

## Use cases
- implement a lorawan end device in c
- lorawan node stack for stm32
- build a class a b c lorawan sensor node
- lorawan certification testing firmware
- learn how lorawan mac layer works
- port lorawan stack to custom mcu

## When to choose
- you need a well-tested open-source LoRaWAN 1.0.4/1.1.0 end-device stack in C
- you are maintaining or studying existing LoRaMac-Node-based devices
- you need LoRaWAN certification reference behavior

## When to avoid
- starting a new design - Semtech recommends LoRa Basics Modem instead
- you need newer LoRaWAN features like Relay or CSMA
- you want a actively developed stack with new features

## Facets
- artifact type: library
- maturity: maintenance
- function: embedded, networking, security, sdk
- domain: iot, embedded-systems, networking
- platform: embedded, iot, c, cpp
- tags: lorawan, lora, end-device, stack-implementation, semtech, loramac, wireless, low-power
