DESCRIPTION
PIN:
KEYVCCGNDRXDTXDSTATESTATE is the Bluetooth status pin,
Output low when not connected, and high when connected KEY is the pin for the AT instruction.
which has the same function as the key。

Button:
Pressing the key is equivalent to pulling the 34-pin high/low, and it is used with the AT command. (Most AT commands require it is effective to send by pressing the button.)

Voltage:
input voltage: 3.2-6V, the power supply comes with an anti-reverse connection, but the reverse connection does not work.

Status indication:
When the master does not record the slave address, it flashes quickly; when it records the slave address, it flashes slowly. The slave is not connected to time. After the connection, both the master and the slave are blinking and stopped.

Interface:
The interface level is 3.2V~6V, which can be connected to various microcontrollers (Arduino, 51AVRPICARMMSP 4730, etc,), 5V microcontroller can be directly connected. Connect directly to the serial port of the microcontroller, cannot pass MAX 232 chip.
