The company specializes in the production of circuit boards Bluetooth module Bluetooth module typically consists of chips, PCB, peripheral devices. Such as BLK-MD-BC04-B Bluetooth module there CSR BC4 Bluetooth chip, MX and Flash welding in 4-layer PCB board, while the PCB integrated PCB antenna six 2.4G Bluetooth circuit board with PCB antenna cost high. While others will have RF power amplifier module circuit board, such as BLK-MD-BC04-L remote Bluetooth module. Due to the different roles of different Bluetooth module and application Shenzhen Bluetooth module circuit board module outer lead pins are not the same. [2 Newell Shenzhen Electronic Technology Co., Ltd Bluetooth RF transceiver has the following characteristics. Bluetooth uses time division duplex transmission scheme, using one antenna using different time intervals for sending and receiving signals, and sending and receiving information to share a channel by changing the transmission direction, to achieve full-duplex transmission; Bluetooth transmission power can be divided into three levels: 100mW, 2.5mW and 1mW. Generally used to send power 1mW, wireless communication distance of 10m, the data transfer rate of up to 1Mb / s. If the new Bluetooth 2.0 standard, the transmission power of 100mW, Bluetooth communication distance can reach 100m six half-holes in the circuit board, the data transfer rate has reached 10Mb / s. In addition, the Bluetooth standard also spurious radiation on the receiving process, the radio frequency tolerance band interference and suppression made detailed provisions to ensure the security of data transmission.
