I am new to robotics and planning my first purchase. I'm looking at the Baby Orangutang B-328. Here is information about the microcontroller: http://www.hobbytronics.co.uk/baby-orangutan-328.

The pin headers come unmounted, so you have to do the soldering yourself. My problem is that I don't know what the pin connections are for. Here is a picture of the board:


Could someone briefly tell me what the different connections are for, or link a website that does?

  • $\begingroup$ Welcome to Robotics Eijomjo, but sadly "How do I use" questions are far too broad to make a good Stack Exchange question. We prefer practical, answerable questions based on actual problems that you face. Feel free to come back again and ask more specific Robotics questions once you have read the Baby Orangutan B Users Guide. For more general electronics questions however, you would be better off asking on Electrical Engineering. $\endgroup$

  • $\begingroup$ Thanks for the correction. I will certainly keep that in mind for future posts. And thanks for the advice! $\endgroup$

  • $\begingroup$ No problem Eijomjo, I always hate closing questions by newcomers to the site, I want people to feel welcome here and I try to avoid putting people off. Ultimately keeping the questions on topic and the quality of questions and answers high will make the site more useful in the long run. I look forward to seeing your future questions. $\endgroup$

1 Answer 1


Look at the bottom of the page on your first link: http://www.hobbytronics.co.uk/baby-orangutan-328. under "Documents relating to the Baby Orangutan B-328".

There you will find links to the Baby Orangutan B Users Guide as well as other useful links.

The user's guide contains the pin descriptions you need on page 5.
