The controller board can be used when the pins on the back of the board are connected to the front is connected to stepper motor drives. the Power of Ramps 1.6 is more larger than Ramps 1.5, the largest power will be up to or 270W. DRV8825 Stepper Motor Driver Control Panel Board Expansion Board Module... Features: Expand to control accessories. 3D Printer Mainboard 3D Printer Upgrade Ramps 1.5 Base on Ramps 1.4 Control Panel Board Expansion Board For Cnc Machine RAMPS 1.4 Control Panel is used as driving shield for 3D printers, and it's easy to stack it onto the MEGA 2560 control board. For Ramps 1.5 control board, They change the original plug-in MOS tube to patch-type MOS tube in order to solve the problem of plug-in MOS tube easy to break, take up a large area, poor heat dissipation , which can improve the stability and aesthetics of the board. The Ramps1.6 controller board is changed the original plug-in MOS tube to patch-type MOS tube. RAMPS 1.4 Reprap 3D Printer Arduino Mega Shield (RAMPS Reprap Printer Generation 6 Controller Board 3D Printer Motherboard Main Control Panel The Sixth Generation Gen6 Motherboard For 3d Printer Control Board Design of Pololu plate pin sockets can be easily replaced or removed for future designs. Santuzza is a young and dynamic brand founded in 2008, We offer an array of affordable products which are mainly used sterling silver and karat gold to make earrings , rings, and pendants crafted in pearls, cubic zirconia , color stones & diamonds The structure almost same as Ramps 1.5 , the difference is Ramps 1.6 have new 2pin connectors, which more simple and convenient to connect, also will not be burnt easily. Ramps 1.6 have a good heat sink above MOS tube in order to give a better function to heat dissipation .
