- | (Preview) | + | Currently, two breakout boards are available for the myCNC-ET15 controller: |
+ | |||
+ | 1) Dedicated ET15 breakout board | ||
+ | 2) ET10/ET15 board (comes with the ET10R5C controller model) | ||
+ | |||
+ | Depending on the breakout board, the ET15 controller will have a different number of I/O ports. Please consult the chart below to find out the necessary model for your setup. | ||
