  • Still did not test circuits, but I believe they are OK. I like that they were packed in electronic's plastic bags, not ordinary plastic (electrostatic discharge). Electronic is neatly soldered, SMD componnents precisely placed... Great value/ price

  • This is perfect to run a CNC machine or a Laser engraver. It works with GRBL or with EstlCAM which I prefer to use. If you plan a project like this buy it !
