- This expansion board is designed for Arduino UNO and other GPS recording expansion board; With two kind GPS antenna interfaces. With multiple IO interface of analog pin.

- Uses active GPS antenna.

- Can connect with Arduino pin(D0-D8 optional) by setting TXD and RxD through jump wire, better expansibility than connecting with D0, D1.

- TF card slot and SPI interface, support Arduino.

- With reset button, can directly reset to Arduino baseboard.
