Exactly as described here, and also including, 1x 100K ohm thermistor, 1k resistor and 2 LED, you need basic soldering skills to solder the power wire! Please use a good power supply and thick copper wire to connect the heat bed. The thermistor is comes not soldered, too !



******   New features in MK2B ******
All features from MK2A and you also can operate this board now with 12v or 24v
- a central mounting hole on the front side to allow for three point mounting. This is much easier for bed leveling in comparison to 4 point mounting. First level the side with two holes and fix in place, then level the side with one hole. A glass plate is highly recommended to provide a truly flat surface and rigidity
- The pads to solder onto have been greatly increased as shown in the picture below. The picture shows the wires prepared for soldering routed through the holes for extra security. This does not remove the need to use proper strain relief.
