Not a buck converter
This is just a LM7805 linear regulator on a pcb with various types of in/out connector types. It's NOT a buck converter as was advertised, so it's efficiency is much lower and a lot of power is wasted as heat when regulating higher voltages. I would not have bought it had I known this. Description is not accurate.

Good Concept, POOR Implementation. Died on the first day! E-paper is SLOW and blurry.
Died on first day of use. Stuck at 5 micron. Cleaned per Yellow Jacket instructions with no luck. Called YJ support and they said "Yep it has a bad microprocessor - get it replaced from the original reseller." So now I'm stuck with a half-finished HVAC install and a busted vacuum gauge.
Also, the e-paper display is very SLOW to update. Also, sometimes it's blurry after updating, then usually clears up later. The whole unit is very sluggish: when you press a button, it takes several seconds for the display to update, so you end up pressing a button several times thinking it didn't 'take'.
A feature that would be really great is the ability to rotate the display 180 degrees. A lot of what I have done with it so far requires the gauge to be pointing to the RIGHT. This makes the display upside down. Since it's a dot matrix display, they should have a button to flip the display by 180, allowing you to read it from whichever side you are on.
Good concept, POOR implementation.

Pleased with this controller
1 von 1 finden das hilfreich So far works fine on NEMA-23 motors. I do wish it had a separate Ground pin for the 5V side, but not a big deal. Adjustable current potentiometer and DIP switches to set microstepping. Add some thermal paste between the chip and heatsink for better thermal performance.
