- COM1/COM2, employ 5pin PicoBlade receptacle connector with TTL voltage level (1.25mm inter-pin distance)

- LED Indicator, shows the operational status (LED1 is data link indicator, LED2 is RTK status, LED3 is positioning status, LED4 is power indicator).

- Host USB port, receptacle USB 2.0 port for external USB Flash disk

- Micro USB, 5V DC power supply
