HC-08 4pin Bluetooth Module without Button

HC-08 Bluetooth UART communication module is a new generation of Bluetooth V4.0 BLE Bluetooth protocol based on the transmission module. Wireless working frequency is 2.4GHz ISM, modulation is GFSK. The maximum transmit power module 4dBm, the receiving sensitivity is -93dBm, and iphone4s can achieve 80 meters of super long-distance communication under an open environment. The module uses the CC2540 chip, the configuration of the 256K Byte space, supports AT command, the user can according to need to change the role and the serial baud rate, equipment name and other parameters, the use of flexible. The module is mainly used for short-range data wireless transmission, such as Bluetooth wireless data transmission, Industrial remote control, telemetry, traffic, underground positioning, alarm, smart home etc. It can also be used as Industrial serial port Bluetooth, Drop-in replacement for wired serial connections. Note: Default pairing code is 1234 Features: Based on TI CC2540 chipset Bluetooth class 2 Industrial level SPP Bluetooth module Integrated chip antenna Industrial temperature range from -40 to +85 Support for on-board applications Modulation method: GFSK Transfer rate: Asynchronous: 6 KBPS Synchronous: KBPS Package Includes : 1 x HC-08 Bluetooth 4.0BLE Serial Port Module.
