Description
If you need to use iphone or ipad to control your arduino project, sh-hc-08 4.0 ble slave module with 6pin baseboard may be a good choice. Fully compatible with ios7.0 or later and iPhone 4s / 5 / 5s 6 / 6s. Also compatible with Android 4.3 or laterse note: if the version of the Android os is less than 4.3. it is not compatibleures: 1,Core module uses SH-HC-08, leads from the module interface includes VCC, GND, TXD, RXD, LED status output pin. 2, led indicate Bluetooth connection status, flashing Bluetooth connectivity, lit the Bluetooth connection and open a port Backplane 3, 3.3V LDO input voltage 3.6 ~6V, the input voltage to prohibit more than 7V! 4, the 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! 5, open to the 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 6, after the pair when full-duplex serial port to 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 . 7, compact (3.57cm * 1.52cm), the factory chip production to ensure the placement quality. And sets of transparent heat shrink tubing, dust and beautiful, and anti-staticHow to Test it: 1, Send “AT” will return ” OK” via serial port. 2, Down LightBlue from appstore,and you will find “SH-HC-08” in list Android devices please download “DSD TECH Bluetooth” or “BLE Scanner” APP.
