I am regretfully useing one of those in the first channel of my G0704 conversion. Be aware that its opto-couplers are slow as hell, and will not transmit a pwm waveform accurately enough to use as spindle control, so that pin has had the opto removed and bypassed. Once that was done, speed is within 5% of requested all up and down the scale. > For the somewhat less > cheap Chinese BOB with more features.

The top cover should have its edges rebated for access to the terminals screws with the cover in place. With the cover in place, the pcb should be well anchored, but it covers the screws. How much do you want for one of those Gregg?, I like it, and can machine the access clearance rebates easily enough. Or maybe just drill holes for the screwdriver to pass thru.
