3D Printer Repra Brainwave Control Panel board Main Board Brief introduction Brainwave is a famous Sanguinololu to Reprap 3D printer exported and used a low-cost controller. The main design goal is to reduce costs, a single screw extruder by a printer, to provide a minimum of components required in the implementation. It can be used to drive a printer rectangular or triangular. Feature Small footprint,: Only 60 mm x 79mm 12V power input Micro USB connector In the board edge connectors, vertical or right angle connector will fit.
