Hello sure, but I am not sure if I understand the question. If you mean how this board get power to work the answer is, through the Arduino.
That is what I meant! Thankyou! :)

Hello all.

This is the final design for my Arduino 4116 Dynamic Ram tester. At least for this version. I can’t wait for my first prototype boards to came and start the testing. After that and if all go smoothly i start the printing for this version. 7~12 dc volt barrel jack fitted in this version to power up the board from external power supply and not only through the Arduino usb, plus i add some protection for the Arduino

The prototype pcb's has not yet arrived, but i decided to do some changes for the final version. I reduced the board size. From 12cm x 11cm it was, it came to be a little less than 10cm x 10cm. This is because the cost of its construction is significantly reduced, but also for reasons of space saving.

There is a manual available and some videos. Looks promising...
The guy has updated the hardware
