Almost done assembling my Nybble, but have a few questions!
1. How do you connect a Raspberry Pi to the Nyboard? I'm thinking of setting it up as described in this post and was wondering how the two boards should be connected.
2. How do you make sure that the y1Pi pieces are flat when they're installed? In all the assembly videos and animations, the y1 pieces seem to be flat (parallel to the belly piece), but when I slotted the y1pi pieces into the shoulder and hip sections, they slant inwards slightly. I tried my best to take a photograph, but the black makes it a bit hard to see. How do you correct this?

More photos below for reference



The y1 pieces will tilt a little bit, and you will install NyBoard on the top side to flatten it. That torsion will help tightening the structure. Insert Pi into the 2x5 socket on NyBoard, then slide in the two clips on both sides. Use screw D to fix them in place.
I'll try that and see how it goes. Thanks for the speedy reply!
Another quick question - are you supposed to solder the 4 pins for the ultrasonic sensor on the same side as the 2x5 socket, or on the opposite side? Seems like both positions are slightly awkward once the RPi is mounted on top of the Nyboard
Also would you have examples for how to manage the cables running from the ultrasonic sensor/head to the board?
If you are going to mount Pi, it's better to connect the sensor with Pi for more computation power.
You can also tilt the pins as below:
you will need several resistors as voltage divider to fit 3.3V logical level of pi
Would this be required for all the pins of the ultrasonic sensor?
no. google “sr-hc04 raspberry pi”
