New at Mouser: Arduino ASX00073 UNO SPE Shield for Edge, Industrial Automation, IoT, and Smart Applications
September 30, 2025 – Mouser Electronics, Inc., the authorized global distributor with the newest electronic components and industrial automation products, is now shipping the new ASX00073 UNO SPE shield from Arduino. The ASX00073 shield brings advanced connectivity to new and existing projects with Single Pair Ethernet (SPE) and RS485.
SPE is a new Ethernet communication standard that enables power and data to coexist on a single pair of wires, referred to as Power over Data Line (PoDL). This allows for faster data transfer and reduced wiring complexity and costs for industrial automation, edge computing, automotive networks, internet of things (IoT), and smart building applications.
Compatible with the Arduino UNO form factor, the ASX00073 shield supports SPI, UART, and I2C, facilitating interoperability with various devices. By incorporating RS485 connectivity, the ASX00073 UNO SPE shield becomes a versatile tool for upgrading RS485 legacy systems or integrating modern technologies with current infrastructures. Additionally, ASX00073 shield features screw terminals for additional connectivity and power options, along with advanced protection, making it ideal for remote industrial monitoring environments and automated control.
Mouser also stocks the Arduino UNO REV 4 Microcontroller Board. The UNO REV 4 board is powered by the Renesas RA4M1 32-bit Arm® Cortex®-M4 processor with 48MHz clock speed, offering impressive processing power, memory capacity, and overall functionality that comes in two versions, the UNO R4 Wi-Fi® and UNO R4 Minima. The UNO R4 Minima delivers cost-effective performance without compromising the microcontroller's core capabilities, while the UNO R4 Wi-Fi features a pre-installed Espressif S3 Wi-Fi module for wireless connectivity. Both are in the same form factor, shield compatibility, and 5V operating voltage as the UNO R3, making it easy to upgrade to the UNO R4 without the need for significant changes or adaptations.
