RAMPS 1.4 1.5 1.6 RepRap 3D Printer Controller Board Shield for Arduino Mega 2560 R3
$1.96 – $3.27
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.
