Figure 8: Top view (left) and the bottom view (right) of the GNSS daughter card
The MTi-7-DK comes with the GNSS daughter card installed in the
auxiliary sensor extension sockets
(P200 and P201). As shown in Figure 8, the GNSS daughter card consists of a GNSS and a barometer
sensor component. The LEDs (Power and PPS) give indication of proper functioning of the GNSS
daughter card. The supplied GNSS antenna can be connected to the SMA connector.
The
auxiliary sensor extension socket
has mikroBUS™ compatible pinning. This enables the user to
connect alternate GNSS daughter card modules with mikroBUS™ pinning to the MTi 1-series Shield
board. The pinning connections for the auxiliary sensor extension socket are listed in Table 7. This
extension only uses the 3.3V supply pin, which is connected to VDDIO. Therefore, make sure that the
VDDIO is within the required voltage range of the GNSS module.
