I'm trying to identify the appropriate connector for this bundle of unterminated contacts, from my HP Stream 14 motherboard.
The number of contacts are:
\$4 \qquad\qquad 29\$
\$5 \qquad\qquad 29\$
The first picture, with unsoldered contacts, was pulled from the internet. The second picture is of my actual motherboard.
The reason for asking is that the Intel Celeron embedded on this motherboard (https://ark.intel.com/products/91832/Intel-Celeron-Processor-N3060-2M-Cache-up-to-2_48-GHz) supposedly has
4 PCIe lanes 1 DisplayPort/HDMI (integrated graphics in CPU) 5 USB ports (some 2.0, some 3.0) 2 SATA 1 UART 1 GPIO.
The screen uses the DisplayPort/eDP. The physical HDMI port is most likely in dual-mode with the DisplayPort above. There are physically 2 USB 3.0 and 1 USB 2.0 ports The keyboard might take up either a USB or the UART or the GPIO. The trackpad might also take up a USB or the UART or the GPIO. The M.2 slot uses 2 of the PCIe lane.
So really, there are more or less:
2 PCIe lanes made unavailable 0 to 2 USB ports (some 2.0, some 3.0) made unavailable 2 SATA made unavailable 0 to 1 UART made unavailable 0 to 1 GPIO made unavailable
So perhaps some of the unavailable lanes above are on the unterminated contacts?
How do I test?
But really, the easier way of going about this is identifying the connector.
