Figure 21: J10 signals
☞
Jumper J10 is not mounted on the C214 board but can be added in the application design – if
needed.
NEO-D9S UART2 is connected directly to ZED-F9R UART2. This allows the two modules to share
correction data directly – without any intervention from NINA-W106.
NEO-D9S USB is connected to the 4-port USB hub IC and is available for connection through the J1
USB connector.
4.4 LARA-R6001D LTE cat 1 modem
The LARA-R6 series comprises multi-band and multi-mode modules that support LTE Cat 1 FDD and
LTE Cat 1 TDD radio access technology with 3G UMTS/HSPA and 2G GSM/GPRS/EGPRS fallback,
which makes LARA-R6 the ideal solution for global and multi-regional coverage.
LARA-R6 is powered from the 3.75 V linear regulator and all IOs are referenced at 1.8 V voltage level
(powered by the V_INT pin). As a result, the level translators are used for all signals shared with the
host.
LARA-R6 is connected to the host through the 8-wire serial port (data lines, hardware flow control
lines and modem status and control lines). LARA-R6 uses DCE notation.
