BLE Module (Bluetooth Low Energy 4.1/Bluetooth Smart) with antenna
WC7220B0

WC7220B0 from Wi2Wi's MCU Embedded Series is a Host-Less Single-Mode Bluetooth Low Energy (BLE) Module with integrated chip antenna. This self-contained BLE module with on-board microcontroller, embedded BLE 4.1 stack and application profiles enables the system to connect to any smartphone/tablet or any other BLE enabled devices in a Personal Area Network (PAN). WC7220B0 being one of the industries smallest BLE module is a subsystem that includes MCU, MAC, baseband, RF front-end, LNA, PA, crystals, filter and EEPROM. This ultra low power BLE module with multiple Power-down modes consumes as low as nano amps which provides excellent battery life and can be powered with a small coin cell battery like CR2032. Extra memory in WC7220B0 - hostless BLE module will enable the system developers to write user application programs and eliminate the need for any external Microcontroller. Additionally, interfaces such as UART, I2C, GPIOs with Analog, Digital and PWM functionality are also available to communicate with external peripherals and sensors. WC7220B0 - standalone ble module is FCC, CE and IC certified and comes in extended temperature grade; -30°C to +85°C.
