Pin NO. | Pin Name | Description |
1 | ANT | Connect with 50 ohm coaxial antenna |
2 | GND | Power ground |
3 | RX_ANT | Transmit antenna switch control pin |
4 | TX_ANT | Receiving antenna switch control pin |
5 | VCC | Connect to the positive power supply 3.3V |
6 | GPIO0 | Connect directly to the GPIO0 pin of the chip |
7 | GPIO1 | Connect directly to the GPIO1 pin of the chi |
8 | GPIO2 | Connect directly to the GPIO 2 pin of the chi |
9 | GND | Power ground |
10 | SDO | 0~VDD V digital output, provides serial readback function to internal control register |
11 | SDI | Serial data input. 0~VDD V digital input. This pin is a 4-wire serial data serial data stream bus. |
12 | SCLK | Serial clock input. 0~VDD V digital input. This pin provides a 4-wire serial data clock function. |
13 | 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. |
14 | nIRQ | Interrupt output pin |
15 | 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. |
16 | GND | Power ground |
