- Reserved GCI like I2C and RS232
- MOSFET 3 MOSFET is applied to the heater/ fan and thermistor circuit.
- Another 5A added to protect the component parts.
- An 11A fuse is added to the hotbed.
- Support 5 stepper drive board
- The adoption of Pin Header as Pololu makes it more convenient to repair or change.
- I2C and SPI are reserved for expanding
- All the MOSFET can be controlled by PWM
- Use the interface of the servo motor to adjust the level of the printing platform automatically.
- Adding an SD module for SD ramps module.
- LED can indicate the status of the heater (the open and close of MOS).
- Expandable to control other accessories.
- Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs.
- 2 stepper motor for Z axis in parallel.
Package Includes :
- 1 x RAMPS 1.4 board, assembled.
