Pin Definitions:
| Number | Pins definition | Description |
| 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. |
