Figure 3: 3-pin header J248 available to set the routing of the UART interfaces on the EVK-R6 for LARA-R6 modules
The other peripherals of the cellular module are available on the dual-in-line male header connectors
(J103 / J104) provided on the top layer of the cellular adapter board ADP-R6.
The lower board is designed to also be used with other u-blox cellular adapter boards. It contains
additional switches, jumpers, connectors, LEDs and parts that are partially described in
or in
this document, because they are intended for use only with other u-blox cellular modules. It is
recommended to leave any additional connector unconnected, and to leave any additional switch in
its default configuration.
