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. |
12 | GND | N/A |
13 | ANT | Pick up the coaxial antenna 50 |
14 | GND | N/A |
