Economical Wireless Solutions

Although the CC2340 modules boast numerous optimized features, their prices have not increased. On the contrary, to ensure widespread utility over varied industries, RF-star CC2340 modules are priced affordably, supporting budget-friendly purchases.

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, SimpleLinkTI 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, while 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 possibilities 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 +125and AEC-Q100 standards and will be available soon.
