AVR
So I have a pile of these NANO-QM871-i1-i5 single board x86 PCs. They have about 8GB of RAM a dual core i5 and all the standard connectivity + more, its rated for industrial temps and conditions. The fun thing about these is the documentation is terrible, its not very clear where the poweron pins are located so anyways posting it here to see if anyone has any experience with these, I have quite a few and I want to get some of them powered on. My plan is to put a few in a box running Ubuntu/Bitwig to host software synths so I can embed and integrate them with my hardware synth setup.

Selling these for 100 bucks a piece , send me a message if you want one !!!

still having this trouble? From all the connectors on the bottom, identify these that are not USB/FireWire/audio/whatever else. Then, get a multimeter out - on these connectors, you need to find the pin(s) that have 3.3V on them (relative to PCB ground) while the board is powered through the connector on the top left. 5V is out, that is likely to be standby power for something (i.e. a front panel USB port). Shorting one of these 3.3V-in-standby pins to ground (through 300ohm resistor if you want to stay safe) should power the board on.

Looking at the datasheet, you should specifically check the header named "Front panel" (on the top of the diagram)

I figured it out for the most part, now its a matter of using them for something. I have 30 of these boards. PM me if you want one and we can work something out ;)

I have these boards and I feel their documentations and customer services are above average. Maybe try here first for user manual: https://download.ieiworld.com/?model=NANO-QM871-i1.

where is the on/off switch header ? The PDF diagram conveniently labels everything on the motherboard except that.
Are you sure? yes | no
You'd pretty much bet the square connector (4 pin) in the upper right is the power. You can verify this by following the ground pane back to that connector and VCC from some component.

Yeah that connector is for powering the baord froma supply, but I want to be able to switch it on. On ATX motherboards that typically is jumping two pins together with a switch. Having trouble figuring out which ones.
