Features of 433MHz RF Module RF4463PRO

Typical Application Circuit of 433MHz RF Module RF4463PRO

Pin Definition 433

Pin NO.	Pin Name	Description
1	GND	Power ground
2	NC	NC
3	GPIO0	Connect directly to the GPIO0 pin of the chip
4	GPIO1	Connect directly to the GPIO1 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
