Pin 1
Figure 3: 3-pin header J248 available to set the routing of the UART interfaces on the EVK for LARA-R6 / LARA-L6 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 / ADP-L6.
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
Figure 1 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.
