PC Engines APU3B2 - 3 LAN / GX-412TC quad core / 2 GB DRAM

This board version is targeted at applications that require two 3G / LTE modems. If you don't plan on connecting two SIM cards, please consider APU2C0 or APU2C4 instead.

• CPU: AMD Embedded G series GX-412TC, 1 GHz quad Jaguar core with 64 bit and AES-NI support, 32K data + 32K instruction cache per core, shared 2MB L2 cache.
• DRAM: 2 GB DDR3-1333 DRAM
• Storage: Boot from SD card (internal sdhci controller), external USB or m-SATA SSD. 1 SATA + power connector. mSATA is shared with miniPCI express.
• 12V DC, about 6 to 12W depending on CPU load. Jack = 2.5 mm, center positive
• Connectivity: 3 Gigabit Ethernet channels (Intel i211AT)
• I/O: DB9 serial port, 2 USB 3.0 external + 4 USB 2.0 internal, three front panel LEDs, pushbutton
• Expansion: 3 miniPCI express (J14 USB or mSATA, with SIM; J15 USB only, with SIM; J16: full miniPCI express, but no SIM, intended for wifi). GPIO header, optional I2C bus, COM2 (3.3V RXD / TXD).
• Board size: 6 x 6" (152.4 x 152.4 mm) - same as apu1d, alix2d13 and wrap1e.
• Cooling: Conductive cooling from the CPU to the enclosure using a 3 mm alu heat spreader (included).

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.
