About Longruner 3D Printer Kit RAMPS 1.4 Controller Board
RAMPS 1.4 Controller Board Update High Quality Ramp Board by changing MOSFET: Old MOSFET IC Model : PDF55N06; Specification: VDSS: 60V; ID:55A New MOSFET IC model: HM60N06; Specification: VDSS: 60V; ID: 60A HM60N06 current up to 60A,More safety Expandable to control other accessories. 3 Mosfets for heater / fan outputs and 3 thermistor circuits. Fused at 5A for additional safety and component protection Heated bed control with additional 11A fuse. Fits 5 Pololu stepper driver boards. Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs. I2C and SPI pins left available for future expansion. All the Mosfets are hooked into PWM pins for versatility. Servo style connectors are used to connect to the end stops, motors, and LEDs. These connectors are rated for 3A, very compact, and globally available. SD Card add on available. LEDs indicate when heater outputs on. Option to connect 2 motors to Z for Prusa Mendel. A4988: Simple step and direction control interface. Can interface directly with 3.3 V and 5 V systems. Over-temperature thermal shutdown, over-current shutdown, and under-voltage lockout. Six different step resolutions: full-step, half-step, 1/4-step, 1/8-step, 1/16-step, and 1/32-step. Adjustable current control lets you set the maximum current output with a potentiometer, which lets you use voltages above your stepper motor's rated voltage to achieve higher step rates. Intelligent chopping control that automatically selects the correct current decay mode (fast decay or slow decay) 45 V maximum supply voltage. Built-in regulator.(no external logic voltage supply needed) Package include: 1 * RAMPS 1.4 controller board 5 * A4988 Step stick Driver 5 * Heat Sink
