I just acquired a N3150B Mini-ITX mainboard to replace a VIA EPIA LN10000EG board in an embedded PC.

Replacing the VIA EPIA with the ASROCK board worked fine, but I am "missing" a connector on the N3150B that has been connected on the EPIA board. On the EPIA borad, there were jumpers that connected the external PS/2 ports for mouse and keyboard to the board's PS/2 controller. One could remove the jumpers for KB_CLK and KB_DATA and connect a keyboard internally. In case of my embedded solution, it was the front panel display with a number of keys that connected to the PS/2 controller this way.

Now the question: Can I connect a keyboard internally on my new N3150B board? Where could I connect KB_CLK and KB_DATA wires to? Can I solder the wires somewhere directly to the motherboard?

Thanks!

P.S. "Missing" keyboard connector aside, the N3150B is so much better than the old EPIA board: way faster, way cooler :-)

Soldering to the board itself would void warranty but if that isn't important to you I guess you could solder the wires directly to the PS2 keyboard header from the under side of the board. Just look up the PS2 connection schematic to see what pins to solder to.

Would the device not work on a USB header? 

I am not overly familiar with what you are trying to do here so that is the best advice I can give, welcome to the forums 

thanks for the immediate reply! 

The "external connection" certainly is an option and before I destroy my board, I probably will go down that road. 

But looking at the N3150B's PCB, the board appears to be prepared to sport a number of additional sockets that are not present on the N3150B though. Some of them are very close to the PS/2 ports. So I was wondering if one of those might be the one I am looking for. 

But one would need "insider knowledge" or detailed info on the board layout to be sure what those unsoldered sockets would be used for.

Thanks again!

Looking at the other Braswell boards it shares the same board design as the N3050B-ITX but that does not have those headers utilized either. I still remember what the PS2 header looks like and it looks like there are 2 headers that could be suitable but I would hazard a guess that they are not and even if they were they likely lack the circuitry to be operable. 

If you want to solder to the board I think your best bet would be to solder directly to the PS2 pins from the IO panel's PS2 ports.

So soldering from below the PS/2 socket or the external solution are the clear favorites. I think I will try the external solution first to see if it yields the desired results. If it does and if it does not look too bad, i will jst leave it that way. If it looks terrible, I will investigate the soldering solution... 

Thanks again for your advice!
