Pin NO.	Pin Name	Description
1	GND	Power ground
2	GPIO0	The control pin of the transmitter switch is connected inside the module
3	GPIO1	The control pin of the transmitter switch is connected inside the module
4	GPIO2	Connect directly to the GPIO2 pin of the chip
5	VCC	Positive power supply 3.3V
6	SDO	0～VDD V digital output, provides serial readback function to internal control register.
7	SDI	Serial data input. 0～VDD V digital input. This pin is a 4-wire serial data serial data stream bus.
8	SCLK	Serial clock input. 0～VDD V digital input. This pin provides a 4-wire serial data clock function.
9	nSEL	Serial interface select input pin. 0～VDD V digital input. This pin provides select/enable function for 4-wire serial data bus. This signal is also used to indicate burst read/write mode.
10	nIRQ	Interrupt output
