100% Brand new and high quality!
With VCC, GND, TXD, RXD, KEY foot for the Bluetooth
Led indicate Bluetooth connection status, fast flash indicates
unpaired, slow flash indicates AT mode, double flash indicates
Backplane settings LDO input voltage of 3.6-6V unpaired current is
about 30mA, paired 10mA, input voltage prohibit more than 7V
absolute prohibition of reverse power!
Interface level 3.3V, can be directly connected the various SCM
(51, AVR, PIC, ARM, MSP430, etc.), the 5V MCU also can be connected
directly, without MAX232 can not go through the MAX232!
Open to effective distance of 10 meters, over 10 meters is also
possible, but not of this the quality of the connection of the
distance do to ensure
The pair later when full-duplex serial use, do not need to know
anything about the Bluetooth protocol, but only supports 8 data
bits, 1 stop bit, no parity communication format, which is the most
commonly used communication format does not support other formats.
Support to establish a Bluetooth connection through AT commands set
the baud rate, passkey, set parameters are saved after.
