Typical Application Circuit of RF Transceiver Module RF4432PRO

Pins of RF Transceiver Module RF4432PRO

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
11	SDN	Chip enable pin. 0～VDD V digital input. SDN=0 in all modes except shutdown mode. When SDN=1, the chip will be completely shut down and the contents of the register will be lost.
12	GND	Power ground
13	GND	Power ground
14	ANT	Connect with 50 ohm coaxial antenna
