Description
TheSi4712/13-B30 integrates the complete transmit functions forstandards-compliant unlicensed FM broadcast stereo transmission. The chip also allows integrated receive power scanning to identify low signal power FM channels. Users must comply with local regulations on radiofrequency(RF)transmission.
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.
