3D Printer Controller Board RAMPS 1.4 Arduino Mega Shield RepRap Model it is mainly designed for the purpose of using Pololu stepper driven board (similar to 4988 driven board). RAMPS can only work when connected to its motherboard Mega 2560 and 4988/DRV8825. Owing to its stability inspiration and great compatibility with the most 3D printer (all RepRap-model such as Prusa i2 and i3). The combination of Ramps1.4 + MEGA2560 + A4988/DRV8825 is becoming a mainstream of DIY 3D printer control board. Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack. Ramps boards are the heart of most DIY 3D printers on the market and a nice clean compact way to integrate all the systems into a compact enclosure mountable format.
1. Standard interfaces (as that of the extruder)2. Reserved GCI like I2C and RS2323. MOSFET 3 MOSFET is applied to the heater/ fan and thermistor circuit.4. Another 5A added to protect the component parts.5. An 11A fuse is added to the hotbed.6. Support 5 stepper drive board7. The adoption of Pin Header as Pololu makes it more convenient to repair or change.8. I2C and SPI are reserve for expanding9. All the MOSFET can be controlled by PWM10. Use the interface of the servo motor to adjust the level of the printing platform automatically.11. Adding an SD module for the SD ramps module.12. LED can indicate the status of the heater (the open and close of MOS).13. Expandable to control other accessories.
