Pin Definitions:

1......GND...... N/A
2......GPIO0......Internal has connected the emission control module feet
3......GPIO1......Internal has connected the receiving control module feet
4......GPIO2......Connect the the chip GPIO2 pins directly
5......VCC...... Connect power positive 3.3 V
6......SDO...... 0 ~ VDDV digital output, provide the internal control of the register serial back to read function
7......SDI ......Serial data input. 0 ~ VDD V digital input. The pins for the 4 wire serial data serial data flow bus.
8......SCLK......A serial clock input. 0 ~ VDDV digital input. The pins provides the 4 wire serial data clock function
9......nSEL......Serial interface choice input pins. 0 ~ VDDV digital input.The pins for the 4 wire serial data bus provides the choice/make can function, this signal is used to indicate a read/write mode.
10......nIRQ......Interrupt output pins
11......SDN......Close input pins. 0 ~ VDDV digital input. In addition to shut down all the mode mode SDN = 0. When SDN = 1 chip will be completely shut down and the content of the register will be lost.v 12......GND......N/A
13......ANT......Pick up the coaxial antenna 50
14......GND......N/A
