This article will help you to understand the models and clear any confusion while deciding system board for your project.


APU2B0/APU2C0/APU2D0/APU2E0


CPUAMD 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.
DRAM2 GB DDR3-1333 DRAM (Non-ECC)
StorageBoot from m-SATA SSD, SD card (internal sdhci controller), or external USB. 1 SATA + power connector
Power12V DC, about 6 to 12W depending on CPU load. Jack = 2.5 mm, center positive
Connectivity2 Gigabit Ethernet channels Intel i211AT
I/O:DB9 serial port, 2 USB 3.0 external + + 2 USB 2.0 internal, three front panel LEDs, pushbutton
Expansion2 miniPCI express (one with SIM socket), LPC bus, GPIO header, I2C bus, COM2 (3.3V RXD / TXD)
Board size6 x 6" (152.4 x 152.4 mm)
FirmwareCoreboot
CoolingConductive cooling from the CPU to the enclosure using a 3 mm ALU Head Spreader (included)


What is the difference between APU2B0, APU2C0, APU2D0, APU2E0?

This is a stripped-down board of actual APU2C2 Board, this board was basic release at the beginning of 2016, by passing the development stages this board finally got some BIOS updates and PCEngines released a revision of this board with integrate blue wire patches into PCB fab (EMI, power-up circuit). This new revision was modeled as APU2C0

All other specifications and core system board remain the same. 

PCEngines again released a revision of this board in the last quarter of 2018 with reduce leakage current between V3 and V3A power rails which could cause problems with SD cards and added options for better compatibility with LTE modems modules. This model was named as APU2D0.

At the last quarter of 2019 PCEngines once again improved board by Changing battery socket footprint to avoid contact problems. Add signal integrity resistor for core voltage control signal.

Other than improvements/updates all other specifications and core system board are same as APU2B0 Board.

Current Production model is APU2E0 (at the time of this article)

What is the difference among APU2B2, APU2C2, APU2D2 and APU2E2?

This board was basic release at the beginning of 2016 same as APU2C0 board and passing the development stages this board finally got some BIOS updates and PCEngines released a revision of this board with integrate blue wire patches into PCB fab (EMI, power-up circuit). This new revision was modeled as APU2C2.
