RepRap Arduino Mega Pololu Shield (RAMPS) version 1.5 for 3D printer. Includes jumpers.

RAMPS plate is a shield for the Arduino Mega2560. The outputs of the Arduino board are redirected to the motor drivers. To have the complete electronics for a 3D printer you need a RAMPS, an Arduino Mega and at least four stepper motor drivers A4988, DRV8825.

The controller creates step-by-step motor control functions preset with the latest imported high-speed chip and uses a combination of software and hardware methods to ensure superior anti-jam performance of the controller.
It also has reverse polarity protection, overvoltage protection, overcurrent protection, absolute guarantee of safe operation of the controller in a variety of hostile factory environments.
Applies to stepper motor control switches, round-trip motion control, fixed speed control. Industrial DKC-1A stepper motor controller features:
- Operating voltage: 5-32 VDC
- Signal entry point for the lower level entry
- Optimization of the acceleration of the S curve
- The maximum output frequency can reach 20 KHz
