M.2 (4G LTE) connector
ERAGON624 SOM to plug 4G LTE modem on Carrier card by placing 75-pin M.2 connector on Carrier
Board Design. This 4G module is interfaced with second downstream port of USB Hub (it can be used to
expand USB ports) through which it is connected to APQ8053 processor, MI2S_2 interface, BLSP4 UART
interface and few other GPIOs of APQ8053 and Dual SIM card connectors (SIM1-J38, SIM2-J36).
