Renesas launches RX23W module with Bluetooth for IoT devices Renesas Electronics has introduced the RX23W module with Bluetooth for IoT devices. The module features the RX23W 32-bit RX MCU which supports fully integrated Bluetooth Low Energy communication and comes equipped with an antenna, oscillator and custom-matched circuit. The new module is certified under Radio Law for multiple countries, including Japan and the United States (Note), and is Bluetooth SIG certified. As a result this eliminates the need for additional RF design work, tuning, or specialized RF knowledge, allowing engineers to use the module as it is, shortening new product development time.
