Ramps is short for reprap Arduino mega pololu shield, 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. RAMPS – RepRap Arduino Mega Pololu Shield, or RAMPS for short. RAMPS – RepRap Arduino Mega Pololu Shield, or RAMPS for short. It is designed to fit the entire electronics needed for a RepRap in one small package for low cost. RAMPS interfaces an Arduino MEGA with the powerful Arduino MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion. Ramps is short for reprap Arduino mega pololu shield, 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 3Dprinter (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. Standard interfaces (as that of extruder) Reserved GCI like I2C and RS232 MOSFET 3 MOSFET are applied to the heater/ fan and thermistor circuit. Adding another 5A 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 servo motor to adjust the level of printing platform automatically. Adding a SD module for SD ramps module. LED can indicate the status of the heater (the open and close of MOS). 2 stepper motor for Z axis in parallel.
