Ethernet Featherwing
Introduction
The Ethernet Featherwing is a powerful and versatile expansion board that adds Ethernet connectivity to any Feather board. With this feature-rich Featherwing, you can easily connect your Feather board to the internet and enable various network-based applications. In this article, we will explore the Ethernet Featherwing in detail and understand its functionalities.
Features
1. Ethernet Controller: The Ethernet Featherwing comes with a high-performance Ethernet controller that supports full-duplex, 10/100 Mbps communication. This allows for fast and reliable data transfer between your Feather board and the network.
2. RJ45 Connector: The Featherwing features an RJ45 connector, which ensures a secure and stable Ethernet connection. It allows you to easily connect the Featherwing to any network using standard Ethernet cables.
3. PoE Compatibility: The Ethernet Featherwing is compatible with Power over Ethernet (PoE) technology. This means that you can power your Feather board using the same Ethernet cable that provides the network connection. It simplifies the setup and reduces the need for additional power sources.
4. MicroSD Card Slot: This Featherwing includes a microSD card slot, which allows you to store and access data directly on the board. You can save logs, sensor readings, or any other data on the microSD card, making it an ideal choice for data logging applications.
5. Real-Time Clock (RTC): The Ethernet Featherwing features a built-in real-time clock. This enables your Feather board to keep track of time even when it is disconnected from the network. The RTC ensures accurate timekeeping and is useful for scheduling events or generating time-based data.
Setup and Configuration
Setting up the Ethernet Featherwing is straightforward and requires minimal effort. Here are the steps to get started:
1. Connect the Featherwing: Plug the Ethernet Featherwing onto your Feather board, making sure all the pins align correctly.
2. Connect Ethernet Cable: Connect one end of the Ethernet cable to the RJ45 connector on the Featherwing and the other end to your network router or switch.
3. Optionally, Connect PoE: If you have a PoE-enabled network infrastructure, you can connect a PoE switch or injector to power both the Feather board and the Featherwing.
4. Initialize the Featherwing: Once the physical setup is complete, power on your Feather board. The Featherwing will automatically initialize and establish an Ethernet connection.
Usage Examples
The Ethernet Featherwing opens up a world of possibilities for your Feather board. Here are a few examples of how you can use it:
