3 suggestions: Search [https://lcsc.com/products/Pin-Headers_644.html](https://lcsc.com/products/Pin-Headers_644.html) for male headers with long pins and [https://lcsc.com/products/Female-Headers_645.html](https://lcsc.com/products/Female-Headers_645.html) for female mating halves. If you can find female headers with long pins then you can stack the boards like this:  Make the boards so that they have a board edge connector at one end and then design a motherboard/backplane that they all plug into like a toast rack. A bit like this (ignore the voltages and master/slave board names: it's from a completely different project):  Use two of the mounting holes on each board: one as the supply and the other as ground then use long bolts/threaded rods and or standoffs as the power connectors between the boards in a toast rack assembly;

@andyfierman  Thank a lot for the input. I apreciate the stacking idea, but in this case would not work so well for me.      I did searched for headers but really didn't find anything what would work.  I thought would be possible to make something like in the image below. But the connection would need to stand up to 6Amps and 5V I found also this images on internet. but I can´t find the parts in LCSC:

Please see this Bug Report: [https://easyeda.com/forum/topic/False-warning-of-Post-Failed-Network-Failed-1952ef73181746f1917f9b58719a3cdf](https://easyeda.com/forum/topic/False-warning-of-Post-Failed-Network-Failed-1952ef73181746f1917f9b58719a3cdf)@leopardi

@leopardi, This would work or use right angle male and female headers? 5V is not a problem. 6Amps can be dealt with by parallel pins, such as using aa 4 pin header with 2 x ground and 2 x 5V pins. Also look at: [https://lcsc.com/products/Mezzanine-Connectors-Board-to-Board_960.html](https://lcsc.com/products/Mezzanine-Connectors-Board-to-Board_960.html)<br> <br>

andyfierman I am replying now without the @ sign. I dont want to connect the board using male and female pin headers because this would meanthat I would habe open contacts (the male headers) from the side that is not connecter. So I will go with the second option, 4 female pin headers (2x 2pin female) on each side, 2 for GND and 2 for 5V.  And the will connect them somehow....   This U-shaped pins we saw at the illustration I coudnt find to buy yet..  and actually i need it printing the PCB, to make sure the measurements are precise. So if I use the C49661 ( [https://lcsc\.com/product\-detail/Female\-Headers\_BOOMELE\-Boom\-Precision\-Elec\-C49661\_C49661\.html](https://lcsc.com/product-detail/Female-Headers_BOOMELE-Boom-Precision-Elec-C49661_C49661.html) ) as described, 2 in each side, 2 pins for GND and 2 Pins vor +5V will it take 6amps? or these are not the right pin headers? Thanks a lot!

Check the current rating in the datasheet: [https://datasheet\.lcsc\.com/lcsc/1811092011\_BOOMELE\-Boom\-Precision\-Elec\-C49661\_C49661\.pdf](https://datasheet.lcsc.com/lcsc/1811092011_BOOMELE-Boom-Precision-Elec-C49661_C49661.pdf)

andyfierman 3 Ampers per pin, understood. thank you for the lesson!
