I have 4 motors and 2 Motor Encoder Pull-up Board, I simply bought a kit from SuperDroid (https://www.superdroidrobots.com/shop/item.aspx/ig32-dm4-4wd-all-terrain-robot-platform/1930/). I recieved 2 pull up boards, Do I need to buy 2 more “Motor Encoder Pull-up Board” or is 2 enough? Secondly, how do I wire this to the arduino? Does anyone here have schematics that they are wiling to share. I don’t seem to be able to find any schematics that explain how to do this. I’m a noob just trying to learn the ropes. Any help would be appreciated.

Each pull-up board will only work for one encoder, so you are correct that you would need 4 pull-up boards for 4 encoders.
However, if you are trying to read the encoder values from an Arduino you should instead use our Encoder Buffer Board. An Arduino can communicate with these boards via a SPI interface. You can buy either 2 dual channel boards (https://www.superdroidrobots.com/shop/item.aspx/dual-ls7366r-quadrature-encoder-buffer/1523/) or one quadruple channel board (https://www.superdroidrobots.com/shop/item.aspx/quadruple-ls7366r-quadrature-encoder-buffer/2418/). The buffer boards include the pull-up resistors for the encoders so you won’t need the pull-up boards if you use these; you just need to close some solder jumpers to enable the pull-ups. We have some links for working with these boards (including a wiring diagram for connecting to the Arduino) on the item pages.
