The Ramps1.6 controller board is changed the original plug-in MOS tube to patch-type MOS tube. Design of Pololu plate pin sockets can be easily replaced or removed for future designs.
Heater and fan MOSFET outputs and 3 thermistor interfaces, 5A additional security and component protection fusion. Simple and convenient Connection, larger power than Ramps 1.5/1.4, Better Heat Dissipation with heat sink.
Servo connectors are used for connecting limit stops, motors and light-emitting diodes. These connectors are gold-plated and have a rated current of 3A, which is very compact.
Incorporating 5A additional security and component protection, heated bed controls additional 11A fuse.
Applied to 5 Pololu stepper drive board, the LED will light when the heater has output, it can be extended to LCD and other parts, choose 2 motors to connect to Z Prusa Mendell.
