Great Board, clean design with quality etching.

Did find the white silk-screen a tad hard to follow.
It would help if http://KCLinear.com/ST25 included the following (which does format pretty with monospace font)

Variable Spindle PWM LZ PZ Pulse Z
Y Limit LY DZ Direction Z

X Limit LX EZ Enable/Disable Z**
Ground G G Ground

Spindle Direction SD PY Pulse Y
Z Limit SE DY Direction Y

Reste/Abort* RA EY Enable/Disable Y**
Feed Hold* FH G Ground

Cycle Start/Resume* CS PX Pulse X
Coolant Enable CE DX Direction X

Reserved R EX Enable/Disable X**
Probe P G Ground

** enable/disable are tied together on X,Y,Z

ST25 - Arduino GRBL Screw Terminal Breakout Board

The ST25 - Arduino GRBL Screw Terminal Breakout Board is easy to assemble with minimal soldering skills. Fits on the Arduino UNO well with little fuss. I'm using the ST25 - Arduino GRBL Screw Terminal Breakout Board to power the two stepper motors on my CNC lathe. Using GRBL 1.1 the ST25 - Arduino GRBL Screw Terminal Breakout Board is laid out for simple wiring to the stepper drivers. I'm going to be repowering my CNC mill using GRBL 1.1 and getting rid of Mach3 so I'll be ordering another of the ST25 - Arduino GRBL Screw Terminal Breakout Boards for that project. Because of the very good quality of the ST25 - Arduino GRBL Screw Terminal Breakout Board I can highly recommend it to anyone who is going to use Arduino and GRBL to power their machines. I say thanks for a great product and I'll be ordering another soon.
