|
Pin description |
|
* VIN (DC power input): |
This is the main DC supply for a 4.5V ~6.5 DC input power. |
|
* TX: |
This is the main transmits channel for outputting navigation and measurement |
data to user’s navigation software or user written software. |
|
* RX: |
This is the main receive channel for receiving software commands to the engine |
board from SiRFdemo software or from user written software. |
|
* GND: |
GND provides the ground for the engine board. Connect all grounds.
