- A core 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.
- The LED indicates a Bluetooth connection status
- Backplane “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!
- Interface level 3.3 V, can be connected directly to all kinds of single chip microcomputer (51, AVR, PIC, ARM, MSP430, etc.), 5 V single chip can be connected directly
- Clearing the effective distance of 10 meters,
