# Specifications

![The image shows a green printed circuit board (PCB) populated with electronic components. Along the top edge, there is a row of black integrated circuits and smaller surface-mount components. A larger black square chip is located in the center. To the right of the center chip are more small black components and a black multi-pin connector. The bottom edge features a row of gold-plated edge connector pins.\n\nVisible text on the board includes:\n*   '180' near the top left corner.\n*   'DTS' centered below the large central chip.\n*   'DTS' to the right, below the smaller chips.\n*   '123456789' printed three times along the bottom edge near the pins.](.sbc-fm-20250516/064b19fbf356c8aea10bab72fdd5980a3af56d5c6be50d9f97051f609a94868f.jpg)

![This image shows a close-up view of the rear I/O panel of a computer expansion card. It features a metal bracket holding three video or data connectors in a row.\n\nFrom left to right:\n1.  **A 15-pin VGA connector (HD15):** This is a trapezoidal connector with three rows of five pins.\n2.  **A 25-pin D-sub connector (DB25):** This is a larger, rectangular connector with five rows of five pins.\n3.  **Another 25-pin D-sub connector (DB25):** Identical to the middle connector.\n\nEach connector is secured to the bracket with two screws. A small portion of the green printed circuit board (PCB) is visible beneath the metal bracket on the left side. There is a small black rectangular component attached to the far left edge of the bracket. There is no visible text in the image.](.sbc-fm-20250516/fe67d04b54adb893141d3c918c0bb509f79bd95f531ff0348234c10b6fc56a0e.jpg)

![Two stacks of server processors are mounted on a green circuit board. Each stack consists of three components stacked vertically: a black processor on top, a white processor in the middle, and a black processor on the bottom. The text 'Intel Xeon E7-4800' is printed on the side of every processor in both stacks. Gold contact pins are visible along the bottom edge of the circuit board.](.sbc-fm-20250516/73d3f30bda622324eb81e5287d752a08a7bab63618aa80872b6c92ce16cf50c3.jpg)
