Manuals, CAD, and software for the AR4. MK5 back through AR2. Match the HMI to the Teensy sketch, and the aux board sketch to that pair.
Make sure you install the latest version sketch that matches the software version you are using - for example when using the latest software version 7.0 you should also install the teensy sketch version 7.0 and for the nano board sketch please use the latest version 2.0. (for version 6.8 - use nano sketch 1.5)
