Description
Function
Main power switch Power on / off the whole evaluation kit
Cellular VCC Jumper socket to provide the 3.8 V supply to the cellular VCC input
Cellular power-on Push button to switch on / off LEXI-R520 modules
Cellular reset Push button to reset LEXI-R520 modules
Cellular UART detach
Slide switch to attach / detach cellular UART from USB / RS232
connectors
Cellular UART routing Slide switch to select cellular main UART routing on USB or RS232
connector
Cellular GPIO detach Slide switch to attach / detach the cellular GPIOs from peripherals:
when detached, the signals are available only on DIL B2B connector on
ADP-LEXI-R520 board
Cellular GNSS detach Slide switch to attach / detach the cellular system to the GNSS module
mounted on the ADP-GNSS: when detached, signals are available only
on DIL B2B connector on ADP-LEXI-R520 board
GNSS BCKP Slide switch to connect / disconnect backup battery to V_BCKP pin of
the GNSS module mounted on the ADP-GNSS
GNSS Tx routing 3-pin header jumper to route and make accessible GNSS UART Tx over
the USB connector on the ADP-GNSS or to use it as Tx data ready for
the cellular module
