 + 
 +//This page is for the latest revision of the myCNC-ET10 control board (revision 3). To find out more about revision 2, please consult the [[mycnc:mycnc_et10_r2|myCNC-ET10-R2 manual]].//  
 + 
 +//Note: The ET12 board is the new updated version of the ET10 controller, which requires unique firmware due to the use of a different chip.//  
 + 
 +The new revision of the breakout board is now compatible with both the ET10 and the ET15 (as an option instead of the native ET15 breakout board). Galvanic isolation on the ADC has been added (highly useful for plasma cutting applications).  
 + 
 +ET10R3C controller specifications: 
 +  * 6 channels pulse/dir high speed differential outputs compatible with RS422 (TIA/EIA-422) standard; 
 +  * 6 channels +/-10V DAC outputs for analogue servo-driver control; 
 +  * 6 channels incremental encoders inpiuts, 4 full ABC encoder inputs, 2 reduced AB encoder inputs; 
 +  * 48 binary inputs (if use with ET10BB breakout - all inputs have galvanic isolation, 12 groups of 4 binary inputs, compatible with NPN & PNP sensors); 
 +  * 24 binary outputs (if use with ET10BB breakout - all outputs are open collector, 24V 0.25A); 
 +  * 4 PWM outputs (if use with ET10BB breakout - all PWM outputs are open collector, 24V 0.25A); 
 +  * 8 ADC inputs (if use with ET10BB breakout - 6 conventional ADC inputs, 1 ADC is differential input 30V, 1 ADC is differential with galvanic isolation for the 0-5V range);
