Product selling point:
1. Wide voltage power supply, easy to use
2. Left and right channel input, sound quality guarantee
3. With regulator interface, the voltage can be adjusted
4. With LED indication at a glance
5. Full inspection at the factory, quality assurance
Pin description (for reference only):
LIN: Audio input, connect the left channel of the earphone.
RIN: Audio input, connect the right channel of the earphone.
Vin: The power supply voltage is 3-5V DC.
GND: Ground.
3V0: This is the regulator interface, which is connected to a 3.3V voltage. If you need a 3V voltage of 100 mA, you can use this regulator voltage.
RST: Reset.
CS: Select pin, used in spi mode. The i2c address is determined. When connected to high level (default), the i2c address is 0x63. If it is grounded or short-circuited, the i2c address is 0x11.
SCL: Clock pin, connected to the microcontroller.
SDA: Data pin, connected to the microcontroller.
GPIO: can be used to flash the LED, the initial state has been set, 3V output.
List:
Transmitter*1
Single row needle*1
