Bluetooth Module for Arduino (3 Pack)

About this item

• The module primarily serves short-distance wireless data transmission applications like Bluetooth, industrial remote control, telemetry, traffic management, underground location tracking, security systems, and smart home technologies.
• Industrial serial port bluetooth, Drop-in replacement for wired serial connections, transparent usage. You can use it simply for a serial port replacement to establish connection between MCU and GPS, PC to your embedded project and etc.
• Using HC - 06 from module , which leads to the interface includes VCC, GND, TXD, RXD, reserved LED state output pin, MCU can state whether the bluetooth is connected through the foot, from machine KEY pin is invalid.
• Works with any USB Bluetooth adapters, running in slave role: Pair with BT dongle. Led indicate Bluetooth connection status, flashing Bluetooth connectivity, lit the Bluetooth connection and open a port Backplane, when the bluetooth connection has not been established by pairing the AT command set baud rate, name, password, and set the parameters of the power save. After the bluetooth connection automatically switch to passthrough mode.
• Interface level 3.3 V, the input voltage 3.6 ~ 6 V, current when the unpaired about 30 ma, matching after about 10 ma, no more than 7 V input voltage, can be connected directly to all kinds of single chip microcomputer, 5 V single chip can be connected directly, without MAX232 couldn't through MAX232.
