I bought the magideal micro usb breakout boards from Amazon, 10 for 6.99 with pin headers. I was pleasantly surprised when they came that they were not separated, and the pitch between boards matched Yuriy's adapter board design. I bent the pins over and rotated them to connect the grounds. The sequence is shown in the first picture. The finished board in the 2nd picture. I finished building my adapter board and soldered the one scales connector board on, and it works perfectly.
