I might buy one of these https://www.pololu.com/product/3117 During shopping cart checkout how do I indicate I want the header for the Rasp. Pi 2 bridge? The product looks like additional headers can be soldered to the board to access Arduino-like features but I can’t find a kit of headers for that. Maybe I’m not meant to do that.
I plan to get a Zumo Chassis Kit https://www.pololu.com/product/1418 some HPCB micro motors https://www.pololu.com/category/174/high-power-carbon-brush-hpcb-micro-metal-gearmotors and add a couple quadrature encoders https://www.pololu.com/product/3081 Will the motors with encoders fit inside the chassis?
I read the robot controller might be able to handle the input from the encoders by using interrupts but then I saw this https://www.pololu.com/picture/view/0J6675 I’m a newbie. Are there enough pins available for input from the encoders? Looks like INT1, INT2, INT6, and some PCINTs are available but I’m not sure those are meant to be used with quadrature encoders. Can I connect a second mini Arduino-like controller to read the encoder input and then pass that info on to the Rasp. Pi or robot controller? Maybe I need a different robot controller.
