Additional Details

The BCM20702B0KWFBG operates in the 2.4 GHz ISM band. It utilizes a Gaussian Frequency Shift Keying (GFSK) modulation scheme for basic rate transmission and Phase Shift Keying (PSK) for EDR. The chip supports Adaptive Frequency Hopping (AFH) to minimize interference with other wireless devices. The integrated MCU allows for custom application development and control. The device is typically surface mounted on a printed circuit board (PCB) and requires external components such as an antenna and power supply for proper operation. Power requirements are typically 3.3V. The operating temperature range is generally between -20°C and +70°C. Additional configuration and programming are usually done via USB or UART interface. The data rate supports up to 3 Mbps using EDR. It's designed to meet regulatory requirements for various regions including FCC, CE, and Japan.
