Pin 1

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 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.
