It also has a rich set of peripherals. Because of its unique ultra-low-power sensor controller, it’s ideal for connecting external sensors, and it is also suitable for autonomous collection of analog and digital data while the rest of the system is in sleep mode.Thanks toitsbuilt-in dual-core low-power processor, users can build a complete system based on their own supporting modules. Weused a 24MHz industrial grade high precision low temperature drift active crystal. The module also supports secondary development. Users can write their own code to achieve the functions Features：The measured communication distance can reach150/300 m; Maximum transmission power of 1.6mW, software multi-level adjustable; Built-in BLE 4.1protocol stack； Built-in 32.768kHz clock crystal oscillator; Support the global license-free ISM 2.4GHz band;Built-in high performance low power Cortex-M3 and Cortex-M0 dual core processor; Rich resources，128KB FLASH，28KB RAM; Support 1.8V~3.8V power supply，power supply over 3.3Vcan guarantee the best performance; Industrial grade standard design, support -40 ~ 85 °C for working over a long time; Support PCB antenna and IPEX interface, users can choose Application：Smart homes and industrial sensors；Security system, positioning system；Wireless remote control, drone；Wireless game remote control； Health care products； Wireless voice, wireless headset；Automotive industry applications RF Parameter Value Remark Working frequency 2402~2480 MHz Default: 2.4GHz (24MHz oscillator) Transmitting power 2 dBm About 1.6mW Receiving sensitivity -97 dBm Air data rate: 1M bps Air data rate 1M bps Please refer to IC datasheet for Blutooth 5.1 Test distance 250m In open and clear air, with maximum power, 5 dBi antenna gain, height of 2m, air data rate: 1M bps Hardware Parameter Value Remark IC CC2640F128RSMR - FLASH 128 KB - RAM 28 KB - Core M3+M0 - Size 14*23 mm - Antenna type PCB/IPEX - Communication interface UART - Package SMD - Electronic parameter Min.
