THE FRITZ!BOX 6890 LTE V2 INTERIOR
The moment you access the interior you’ll notice a large black heatsink.
Under that black heatsink AVM has placed the AnyWan GRX550 dual-core network CPU with the 512MB DDR3L SDRAM by NANYA and the 512MB flash memory by Macronix (there’s also a 4th module here which I couldn’t identify in time).
Other components include the L830-EB-11 4G cellular module (supports LTE FDD/WCDMA) by Fibocom, QCA9985 802.11n 2.4GHz and QCA9984 Wave-2 802.11ac 5GHz dual-band 4x4 radios by Qualcomm, Spartan-6 FPGA by Xilinx and the SC14446 DECT module by Dialog.
