3D Printer Controller Board RAMPS 1.4

3D Printer Controller Board RAMPS 1.4 Arduino Mega Shield RepRap Prusa 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 mother board Mega 2560 and 4988/DRV8825. Owning to its stability in operation and great compatibility with most 3D printer (all reprap-model such as pursa 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.

Specifications:

• Supply Voltage : 12 V.
• Fused at 5A for additional safety and component protection
• Heated bed control with additional 11A fuse
• 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.
• 2 stepper motor for Z axis in parallel.

Features:

1. Standard interfaces (as that of extruder)
2. Reserved GCI like I2C and RS232
3. MOSFET 3 MOSFET are apply to the heater/ fan and thermistor circuit.
4. Another 5A added to protect the component parts.
5. An 11A fuse is add to the hotbed.
6. Support 5 stepper drive board
7. The adoption of Pin Header as pololu makes it more convenient to repair or change.
8. I2C and SPI are reserve for expanding
9. All the MOSFET can be controlle by PWM
10. Use the interface of servo motor to adjust the level of printing platform automatically.
11. Adding a SD module for SD ramps module.
12. LED can indicate the status of the heater (the open and close of MOS).
13. Expandable to control other accessories.
