2.2 Switch
Figure 2-2 Switch
The EVB board has three switches for the UART and Power of GPS module. All these three switches
should turn left when connect the module to the computer through the Micro-USB, like getting the
NEMA data or downloading the software.
2.3 USB Interface
The EVB board only provides one way for data communication. Micro-USB interface can also supply
the main power for the EVB, not need another power. You can cut the UART communication via the
switch (4, 5) and the power supply of GPS module via the switch (6).
2.4 Antenna Interface
Both the active antenna and passive antenna can be selected for the external antenna. Please note
the N10 and N20 have the different match circuits.
