Connector Summary
Micro-SD Flash and Cellular Nano SIM Expansion Socket (J1)
Flash expansion is possible by installing an industry standard 11mm by 15mm Flash
card into the socket. The Micro-SD Flash card cannot be installed or removed with
power applied to the SBC. The Micro-SD and Nano SIM sockets are combined. The
command signal is routed to the processor.by default. The Nano SIM socket is routed to
Mini-PCIe socket J10.
Optional GPS MMCX or u.FL Antenna (J2)
The optional GPS feature includes an antenna connector for an externally mounted
passive or active antenna. The 50 Ohm MMCX antenna connector (standard loading
option) is a vertical mount Molex 73415-2061, or equivalent. The 50 Ohm U.FL
