How to interface With Microcontroller

Note 1: This is a single unit only. We recommend the purchase a USB dongle to interface to a computer if you do not already have access to a computer with Bluetooth connectivity.

Note 2: Do not attach this device directly to a PC RS232 Port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer

Note 3: I/O Pins are not 5V Tolerant , use level converter for interfacing with 5V Microcontrollers
