CEL CMP4010 Wi-Fi®+ BLUETOOTH® Connectivity Modules are low-power, feature-rich, highly efficient modules built for harsh environments. These modules are designed around the RTL8721 SoC from Realtek and provide single-stream 802.11n + BLE v5.0 connectivity. The CMP4010 modules are dual-core devices that feature a KM4 MCU, designed by ARM and Realtek for battery-powered Wi-Fi devices. These connectivity modules offer SoC shutdown modes and MCU deep-sleep modes that minimize current consumption and achieve a maximum battery life. Typical applications include IoT-connected homes with lights, switches, outlets, circuit breakers, safety devices like CO2/smoke detectors, residential HVACs with thermostats, AC units, furnaces, and building automation.
