This week Colorful has introduced a uniquely designed motherboard, created specifically for the professional miner. One of the first things most will notice is this doesn’t look like most motherboards we see on the market. Instead of conforming to any particular form factor, the C.J1900A-BTC Plus V20 breaks that mold and gives us a markedly rectangular shaped board with a total of nine full-length PCIe slots. Eight of the slots can be used for installing mining graphics card of choice while the blue slot in the middle is where the Celeron J1900 SoC resides on its own PCIe card. The SoC itself has a DDR3 SO-DIMM slot, a mSATA slot, and regular SATA for storage; it also contains the board’s connectivity like networking, USB, and video output.
