 ===== myCNC-ET6 CNC controller =====
+^^ myCNC-ET6 controller specifications ^^
+| Number of motor outputs | 6 |
+| Motor driver outputs | pulse-dir, differential line driver outputs compatible with EIA RS-422 Standard |
+| Maximum pulse frequency | 3 MHz |
+| Binary inputs | 8x galvanic isolation, PNP/NPN sensor compatible |
+| Binary outputs | 2 relay outputs, 2 open collector outputs |
+|PWM outputs | 3x - open collector |
+| RS485/RS422 | 1x RS485 with Modbus ASCII/RTU implementation |
+| Computer connections | Ethernet (PC/ARM, Linux, MS Windows) |
+//Note: The ET8 board is the new updated version of the ET6 controller, which requires unique firmware due to the use of a different chip.//

 ==== Power supply connection ====
@@ Line 9: / Line 21: @@
 V DC is used to supply myCNC-ET6 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 controller based kit with single board computer and 15'6" TFT screen. However, step-down converters on the ET6 board consume start current about 1.5A and 24V/1A power supply might be not enough to supply the single ET6 board.

 ==== ET6 control board firmware reflash ====
+//**WARNING:** Unlike updating the myCNC software, the firmware CANNOT be downgraded after a reflash. The myCNC team recommends reflashing the control board firmware as a last resort only, and recommends seeking an explicit confirmation from the support team that the firmware reflash is warranted in order to avoid issues.//
+:!: //**NOTE:** Make sure to select the firmware for the correct version/revision of your board! Firmware for ET6 boards R1-R3 and ET6 boards R4-R6 (also known as the ET8) are __DIFFERENT.__
+Flashing incorrect version of the firmware will result in a non-functional board. If you're unsure of your board version, please contact myCNC Technical Support prior to the reflash://
