PC Engines APU.3A2
The APU.3A2 board version is targeted at applications that require 2 3G / LTE
modems. SIM sockets can be swapped under GPIO control, enabling failover between two different networks even when only one modem is used. Another feature is the build option for a regular PCI express slot on the side.
