6、模块管脚分配
Pin NO. | Pin Name | I/O | Description | Remark |
1 | GND | I | Ground | Assure a good GND connection to all GND pins of the module,preferably with a large ground plane. |
2 | TXD | O | Serial Port | UART, leave open if not used, Voltage level referred VCC_IO. Can be configured as TX-ready indication for the DDC interface. |
3 | RXD | I | Serial Port | UART, leave open if not used, Voltage level referred VCC_IO |
4 | TIMEPULSE | O | Timepulse Signal | Leave open if not used, Voltage level referred VCC_IO |
5 | EXTINT | I | External Interrupt | Leave open if not used, Voltage level referred VCC_IO |
6 | V_BCKP | I | Backup Supply Voltage | Backup supply voltage input pin. Connect to VCC_IO if not used. |
7 | VCC_IO | I | VCC_IO | IO supply voltage. Input must be always supplied. Usually connect to VCC Pin 8 |
8 | VCC | I | Supply Voltage | Provide clean and stable supply. |
9 | RESET | I | Reset | Reset |
10 | GND | I | Ground | Assure a good GND connection to all GND pins of the module,preferably with a large ground plane. |
11 | RF_IN | I | GPS signal input from antenna | The connection to the antenna has to be routed on the PCB. Use a controlled impedance of 50 Ω to connect RF_IN to the antenna or the antenna connector. DC block inside. |
12 | GND | I | Ground | Assure a good GND connection to all GND pins of the module,preferably with a large ground plane. |
13 | ANT_ON | O | ANT_ON | Active antenna or ext. LNA control pin in power save mode.ANT_ON pin voltage level is VCC_IO |
14 | VCC_RF | O | Output Voltage RF section | Can be used for active antenna or external LNA supply |
15 | V_ANT/NC | I | Antenna Bias Voltage | Connect to GND (or leave open) if passive antenna is used. If an active antenna is used, add a 10 Ω resistor in front of V_ANT input to the Antenna Bias Voltage or VCC_RF |
16 | SDA2 | I/O | DDC Pins | DDC Data. Leave open,if not used. |
17 | SCL2 | I | DDC Pins | DDC Data. Leave open,if not used. |
18 | Reserved | - | Reserved | Leave open |
