Q. I have used this circuit for my class year10 in the past and it was very beneficial to explain the function of components and somewhat the circuit. There had been limitation to explanation in detail because of no circuit availability. Would it be possible to have a circuit diagram of this project. to expand it further for educational point of view, it would be really useful.
A. Hi Shakeel. Thank you for your question. Unfortunately we do not have a published circuit diagram, all the available information is in the data sheet.

Q. What are you meant do with all the metal clips?
A. Hi Jack. Thank you for your question. The clips go on the wires then they go into the plastic housings to make up the connectors that plug into the board.
