  • New Product – Mouser Now Shipping Arduino UNO R4 for Industrial Automation and IoT Prototyping

Mouser is now stocking the UNO R4 microcontroller board from Arduino. The UNO R4 is powered by the Renesas RA4M1 32-bit Arm® Cortex®-M4 processor, featuring a clock speed of 48 MHz for higher processing power. The Arduino UNO R4 is offered in two variants, the basic UNO R4 Minima and the comprehensive UNO R4 WiFi, to meet the budgetary and creative needs of the user. For users seeking a boost in processing power without the additional features, the UNO R4 Minima provides a cost-effective option. The UNO R4 WiFi includes an Espressif S3 Wi-Fi module for Wi-Fi and Bluetooth® Low Energy connectivity. The UNO R4 maintains the same form factor as the UNO R3, ensuring compatibility with existing shields and accessories. The UNO R4 microcontroller board offers an exceptional prototyping and embedded platform for a wide range of applications, including industrial automation, Internet of Things (IoT) devices, robotics, weather monitoring, smart agriculture, and artificial intelligence (AI).

  • New Product – Mouser Now Shipping Amphenol’s New T6743-40K-E Automotive CO2 Sensor, Monitoring Human and Pet Occupation of Parked Vehicles

Mouser is now stocking the T6743-40K-E Automotive CO2 Sensor from Amphenol Advanced Sensors. The T6743-40K-E is a nondispersive infrared (NDIR) CO2 sensor that implements a single-channel diffusion sampling method for automotive heating, ventilation and air conditioning (HVAC) applications, including automatic fresh air control and safety sensing for CO2 refrigerants. The CO2 sensor can also provide an important safety feature by monitoring parked vehicles and triggering an alarm if human or pet occupation is detected. The T6743-40K-E can be used to detect in-cabin CO2 levels to prevent driver drowsiness. The device can also be used to reduce variations in heating and cooling in-cabin through demand control ventilation (DCV). Using Amphenol Advanced Sensors’ CO2-based ventilation control, the air is continually monitored, and the influx of outside air is taken into account, eliminating the need for the air conditioning system to bring air in mechanically. Along with the patented ABC Logic™ lifetime calibration warranty, its low power consumption, compact design and simple product integration make the T6743-40K-E an ideal gas-sensing solution.

  • New Product – Mouser Now Stocking CEL CMP961x Wireless Modules, Providing Wi-Fi 6 and Matter Compatibility

Mouser is now stocking the CMP961x Wi-Fi® and Bluetooth® modules from CEL (California Eastern Laboratories). These modules are based on NXP Semiconductors’ IW611 and IW612 wireless system-on-chip (SoC) and deliver the performance and network optimization capabilities of Wi-Fi 6 and Matter, a new connectivity standard for IoT communication across smart devices in healthcare, medical devices, building automation, retail/POS terminals, security, video cameras, and smart home applications. The CEL CMP961x modules offer flexibility to OEMs and users to leverage other lower bandwidth and longer-range protocols like Bluetooth Long Range to address applications that have other demands and needs. Coexistence support for dual/tri-radio protocols is available to enable multiple networks and applications. With +20-dBm output power, the CMP961x modules deliver best-in-class range and coverage, which enhances throughput, lower latency, reduced power consumption, faster OTA firmware updates, and better network reliability. The CMP961x modules are versatile and ready for integration with almost any host platform, including microcontroller or microprocessor architectures.
