# `renard-phy-s2lp` - Sigfox Protocol Physical Layer for S2-LP



`renard-phy-s2lp` is an open source physical layer implementation of the Sigfox protocol's uplink and downlink for STMicroelectronics' S2-LP ultra-low power transceiver chip. It uses [`librenard`](https://github.com/Jeija/librenard) internally for encoding and decoding of Sigfox frames. `renard-phy-s2lp` only supports regulatory zones "RC1" (Europe / Overseas France / Middle East and Africa) and RC2 (North America and Brazil).

It does not directly interface with the S2-LP, but through a Hardware Abstraction Layer (HAL). Moreover, it only depends on functionality provided by the C standard library. This makes it possible to port this driver to various different Microcontroller platforms and processor architectures.

Currently, the following hardware abstraction layers (with their respective demo applications) exist:
