 ===== myCNC-ET15 CNC controller =====
-(Preview)
+Currently, two breakout boards are available for the myCNC-ET15 controller:
+) Dedicated ET15 breakout board
+) 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.
