2AWD9-BT05-COOLWAVEBLE module

Coolwave Communication www.coolwaveasia.com [email protected] CWBT05 Ultra Low Power System-on-Chip Bluetooth 4.2 Module General Description CWBT05 is a high performance, low power radio transmit and receive system module use Realtek BLE 4.2 RTL8752CGF as the controller chips. It has the smallest volume package in the industry, and size is 17*24.7mm, suitable for most applications which pay more attention to the size. This module has integrated the complete standard low energy Bluetooth 4.2 protocol. Customer's MCU could connect to the module by UART port, and it will automatically send a broadcast code after the module starts. As the master, APP device can scan and search the broadcast from module in order to establish the connection. After success, it can conduct two-way communication link with mobile device APP by serial port. Through UART interface, the user can exchange data or control the communication parameters of module. The meaning of data is defined by the upper application user. The mobile device can operate to the module through APP, and the data will receive by the module and pushed through UART MCU. After the module received a data packet from the client MCU serial port, it will be automatically forwarded to the mobile device.

RF EXPOSURE DEFINE The corresponding SAR Exclusion Threshold condition, listed below: 1) The 1-g and 10-g SAR test exclusion thresholds for 100 MHz to 6 GHz at test separation distances ≤ 50 mm are determined by: [(max. power of channel, including tune-up tolerance, mW)/(min. test separation distance, mm)] ·[√f(GHz)] ≤ 3.0 for 1-g SAR and ≤ 7.5 for 10-g extremity SAR,16 where  f(GHz) is the RF channel transmit frequency in GHz  Power and distance are rounded to the nearest mW and mm before calculation  The result is rounded to one decimal place for comparison The test exclusions are applicable only when the minimum test separation distance is ≤ 50 mm and for transmission frequencies between 100 MHz and 6 GHz. When the minimum test separation distance is < 5 mm, a distance of 5 mm is applied to determine SAR test exclusion. 2) At 100 MHz to 6 GHz and for test separation distances > 50 mm, the SAR test exclusion th…
