24V DC is used to supply myCNC-ET control board. Power consumption depends on external peripherals you have connected to open collector outputs and +12V/+5V outputs. Normally power supply 24V/2A should be enough to power up the controlller based kit with single board computer and 15'6“ TFT screen. However, step-down converters on the ET6 board have start current about 1.5A and 24V/1A power supply might be not enough to supply the single ET6 board.
ET6 has 6 channel pulse/dir outputs, 3MHz max pulses frequency.
ET6 pulse dir outputs conforms RS422 standard and compatible with most of servo and stepper drivers (line driver with paraphase signals positive and negative polarity). Internal schematic for pulse-dir is shown on a picture below.
ET6 board contains 7 output pins-
WARNING: ET6 board rev.1 has Output pin names printed on Botton side of the board. This names are NOT correct and differs from actual output addresses. Please check table below to find out actual output address

Schematic for ET6 outputs is shown below
Connector pinouts for ET6 outputs pin shown on a picture below
ET6 control board has 8 galvanic isolated binary inputs, 2 groups of 4 inputs each. Each group has separate power supply pins so inputs can be powered from different power sources. Using PNP and NPN sensors simultaneously if possible too.
Schematic for ET6 inputs is shown below
myCNC-ET6 control board has RS485 bus connector. Modbus ASCII/RTU and Hypertherm Serial communication interfaces are implemented in myCNC-ET6 control board.
RS485 connector pinout shown below
myCNC-ET6 control board has DAC output for spindle speed control. DAC output range is 1..15V Actual Max DAC voltage (ie 10V, 5V, 6V) can be setup in the myCNC control software.
