8+
This library implements the **10BASE-T1S** standard (Single Pair Ethernet) for selected Arduino boards.
9+
10+
It enables low-speed Ethernet connectivity over a single twisted pair, ideal for industrial and automotive applications.
11+
12+
### What is 10BASE-T1S?
13+
10BASE‑T1S is an Ethernet physical layer standard defined by IEEE (part of IEEE 802.3cg) that enables Ethernet communication over a single twisted pair cable at speeds up to 10 Mbps.
14+
15+
## 📖 Documentation
16+
For more information on the features of this library and how to use them please read the documentation [here](./docs/).
17+
18+
## ✅ Supported Boards
19+
20+
This library was tested and validated on the following Arduino boards:
21+
- [Arduino Zero](https://store.arduino.cc/products/arduino-zero)
22+
- [Arduino UNO R4 WiFi](https://store.arduino.cc/products/uno-r4-wifi)
23+
- [Arduino UNO R4 Minima](https://store.arduino.cc/products/uno-r4-minima)
24+
25+
> [!IMPORTANT]
26+
> These boards do not include a native 10BASE‑T1S PHY or transceiver.
27+
To enable Single Pair Ethernet communication, you must connect an external and compatible 10BASE‑T1S transceiver to your board via SPI.
28+
29+
> [!NOTE]
30+
> The library may work on other boards, but they are not officially supported.
