Pin Configuration

Serial Mode

1). Serial Control Commands

2). Serial Query Commands

AD Key Mode

We use the AD module keys, instead of the traditional method of matrix keyboard connection, it is to take advantage of increasingly powerful MCU AD functionality, Our module default configuration 2 AD port, 20 key resistance distribution.

Note: Short press is for Preious/Next, and long press is for Vol-/Vol+

Connection Diagram with Arduino

Note: For simple use, the upper diagram is okay, but it would be better and more stable if you attach a 1K resistor to the TX pin.
