 ===== myCNC-ET15 CNC controller =====
-(Preview)
+Currently, two breakout boards are available for the myCNC-ET15 controller:
+) ET10/ET15 board (comes with the ET10R5C controller model)
+) Full dedicated ET15 breakout board
+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.
+^ Specs ^ Model 1 ^ Model 2 ^

+| Pulse-dir | 6 channels, up to 3MHz | 8 channels, up to 3MHz |
+| Analog -10V...+10V outputs | 6 channels | 8 channels |
+| Galvanic isolated inputs | 48 | 64(72) |
+| Encoder inputs | 4+2 channels | 8 channels |
