I am very confused about a lot of things and im hoping there are some answers. the first question I have is soldering mandatory? can you finish without soldering? if not what do I need to solder and where. also where do I plug in the ultra sonic sensor? how do I plug in the battery pack to the nyboard? how do I connect the controller? and also a basic understanding of where to start with uploading the code in an easy way. I know im asking for a lot but honestly I know nothing about coding and I REALLY didn't know what I was getting into when I bought this. nevertheless I am VERY excited for the end product and I hope I can figure it out. if anyone is willing to answer this rather long list of questions thank you so much and I hope I can finish this. thanks. (FYI I have the Nyboard VO,2. I have not attached my raspberry pi. also I have downloaded everything from GitHub and I connected my nibble to my computer. I also downloaded Arduino sketch. I just need to know what to do from there.)

Hi @Rongzhong Li in the Google doc, you refer to this link: https://www.petoi.com/forum/clinic/placement-of-raspberry-pi-3b for info on how to configure and place the RPi. Has the info moved or do you have a working link? Finally, will there be any issues with using an RPi 4B?

could someone please send me a picture of where I plug in all the cords on the Nyboard VO.2. the only pictures were for VO.1. I also especially need to know where to plug in the sensor on the head. thanks
