RF-star Unveils New CC2340R5 Bluetooth 5.3 Modules With Affordable Wireless Innovation

New CC2340 Series Family — CC2340R5 Bluetooth 5.3 Low Energy Modules RF-BM-2340B1I, RF-BM-2340A2, RF-BM-2340A2I and RF-BM-2340C2 Are In Stock Now!

RF-star, a leading RF wireless modules manufacturer, is thrilled to announce the arrival of the new CC2340R5 Bluetooth 5.3 Low Energy (BLE) modules. Four types are in stock now-RF-BM-2340B1I, RF-BM-2340A2, RF-BM-2340A2I and RF-BM-2340C2. The alternative RF antennas and small different packages allow CC2340R5 modules to deliver industrial-grade performance, ultra-low-power consumption and robust connection for medical devices, building automation, consumer electronics, energy storage systems, and even vehicles.

The introduction of these four items further extends the CC2340 series family, starting with the initial release of the CC2340R5 module RF-BM-2340B1 in 2023. In the marketing of RF-BM-2340B1 modules, they have gained recognition and favor among global customers and developers.

Delving into why the CC2340 series modules are gaining popularity, let's explore their key features and benefits, including an optimized 2.4GHz RF transceiver, industrial-grade performance, rich resources, user-friendly design, and easy-to-use software and tools.

Economical Wireless Solutions
While the CC2340 modules boast a plethora of optimized features, the best part is that their prices remain affordable, making them accessible across industries.

Hence, RF-star CC2340 series modules cater to multiple burgeoning fields by their versatility, such as:

  • Medical Devices: The CC2340 modules' cost-effectiveness, low power consumption, and robust RF performance position them as an attractive choice for designs like CGMs (continuous glucose monitors), insulin pumps, blood glucose monitors, medical sensor patches and wearable fitness.
  • Building Automation: The impressive output power of up to +8 dBm and multiprotocol including BLE 5.3, ZigBee 3.0, SimpleLink™TI 15.4-stack, and Proprietary systems make the RF modules perform well in wireless environmental sensors, fire safety systems, electronic smart lock, etc.
  • Consumer Electronics: The small size of BLE modules enhances the aesthetics of the final products. The exceptionally low power consumption ensures prolonged and stable operation after one charge. At the same time, the affordable price adds an enticing allure for seamlessly integrating CC2340R5 modules into personal electronics, for example, keyboards and keypads, electronic and robotic toys, and smart trackers.
  • Energy Storage: The imminent release of the Thread and Zigbee SDK, coupled with the existing BLE stack, will open up new horizons for the energy storage industry. As a result, the CC2340R5 module serves as an ideal cost-effective wireless connectivity solution for EV chargers, Battery Management Systems (BMS), and microinverters.

Furthermore, the upcoming automotive-grade module RF-BM-2340QB1 based on the TI CC2340R5-Q1 chipset, meets the highest +125℃and AEC-Q100 standards and will be available soon.
