Prevent electrostatic v3 bluetooth headset Wireless Modules
Bluetooth V3 Bluetooth module uses a unique double-layer board design that is beautiful, but also to prevent electrostatic damage to the module. Designed two power input ports, respectively, for a wide supply voltage (3.5V ~ 8V) and 3.3V power supply, suitable for all occasions. STATE and the LINK LED is clear and bright display module status and connection status. It comes with a highly efficient on-board antenna, signal quality, launch distance, transparent serial Bluetooth adapter with a variety of Bluetooth cell phone paired to facilitate the secondary development. The module has two sets of DIP switches, you can set the module status LED Off switch to turn off the LINK light to enter the power saving mode, AT Mode switch causes the module to enter the AT command mode, AT commands to modify the baud rate and master and slave mode. Modules and two modules were set mainly from the module, you can free matching for data transmission, suitable for data communication between two microcontrollers.
