Arduino Uno SPE Shield
Available with a lead time
Expect dispatch between Aug 14 and Aug 18
Designed to unlock the full potential of your Arduino UNO R4, the Arduino UNO SPE Shield brings professional-grade connectivity to your projects in both the maker and the industrial world. It enables high-speed data transmission and power delivery over a single twisted pair cable thanks to integrated 10BASE-T1S Single Pair Ethernet (SPE) with Power over Data Line (PoDL) capabilities, using Microchip’s LAN8651B1 component. This dramatically reduces wiring complexity and cost, while enhancing deployment speed and system flexibility.
Its built-in RS485 interface allows seamless integration with legacy systems – making it an ideal bridge between existing infrastructure and emerging technologies. Whether you’re retrofitting industrial machines, building smart energy monitoring systems, or prototyping advanced IoT devices, the SPE Shield simplifies communication between modern or legacy equipment.
Engineered for ease of use, the shield offers plug-and-play compatibility with the Arduino UNO R4 family and is supported by a dedicated open-source Arduino library, ensuring a fast and frustration-free development experience.
Key benefits
- Single Pair Ethernet with PoDL: Enjoy fast, stable data and power delivery through a twisted pair cable.
- Dual communication support: Combine modern 10BASE-T1S connectivity with legacy RS485 for maximum versatility.
- Simplified wiring: Reduce material costs and complexity in smart building, automotive, and industrial environments.
- Retrofit-ready: Upgrade RS485-based systems with next-gen features without replacing infrastructure.
- Plug-and-play experience: Compatible with Arduino UNO R4 and supported by a dedicated Arduino library.
Application examples to explore
- Smart factory automation: Connect sensors, actuators, and legacy equipment across the floor with a single-cable solution.
- Smart grid monitoring: Transmit energy data from meters and inverters to the cloud via SPE, while integrating RS485 legacy devices.
- Automotive systems: Combine ADAS, infotainment, and control units using SPE, and monitor legacy components via RS485.
- Building management systems: Integrate lighting, HVAC, and security systems into a centralized controller with SPE and RS485.
- IoT prototyping: Accelerate the development of connected devices with fast data transfer and support for legacy peripherals.
