Bittle wiring!

Hi, I am building a bittle which uses a biboard!

I cannot see a revision number on the board so uncertain as which bi board I have!!!!

My problem is that I am unclear on how to physically connect the servos!

There are 4 blocks of pins with a 3x3 layout,but no indication of orientation??

Do the srvo cables connect vertically or horizontally & are they ordered from top to bottom or vv or if vertically which side to side??

I don't want to burn out myservos by connecting them incorrectly so am stuck until I get some guidance!!

Thanks

Moving on from that my servos do not have a brown they have black red and white!! I assumed rightly or wrongly that black=brown!

The head servo is working so i assume that is correct!

None of the other servos seem to working, by that I mean they do move when powered on but do not seem to respond to the +/- slider in the config!! Tried with the petoi app on both a tablet and a phone!!

Need to strip it down again to check the wiring is ok, but is there an easy way to determine if the servos are OK?

Thanks

There should be a firmware uploaded when we tested the board. Can you open the serial monitor of Arduino IDE to see the printed messages? A screenshot or video will be more informative.

I haven't set up the arduino environment yet, was waiting till I had finished building the kit!!I don't have a windows or Mac in regular use as I use chromebooks and tablets for browsing, email etc! That is another problem in my opinion with your software? Why is it limited to windows or Mac? If it was browser based for example it could be used on anything! I shall have to sent up a totally separate environment that will only be used for programming this robot!

The community of Arduino developers is mainly based on Windows and Mac. You can try the ChromeOS routine to set up the Arduino environment. https://docs.petoi.com/arduino-ide/upload-sketch-for-nyboard#connect-the-uploader-sometimes-referred-to-as-the-programmer

Ok, that doc says the brown wire is closest to the board which implies vertical orientation! Would have been nice if that was emphasised in the build instructions! Maybe a picture showing the cables connected!

I do not have a photo of the board, but can take one if needed! Are there variations in the biboard?

Thanks
