RAMPS 1.4 Board Red For Mega 2560 R3:
-It has Cartesian robots and regulations of the extruder.
-Extended to control other accessories.
-Heater / MOSFET outputs and three fan thermistor circuit.
-Integration of additional security 5A and component protection.
-Control of additional heating bed 11A fuse.
-Suitable for 5 Pololu stepper driver board.
-Pololu board pin socket, so they can be easily replaced or removed for future designs.
-I2C and SPI pins left for future expansion.
-Hooked into all MOSFET PWM pin versatility.
-Servo type connector is used to connect to the end stop , the motor and the light-emitting diodes. --These connectors are gold-plated , rated current of 3A, very compact.
-On the SD card to add - is now available from the Kliment - Sdramps.
-LED indicate when the heater output.
-Option 2 motors connected to Z Prusa Mendel.
RepRapDiscount Full Graphic Smart Controller LCD12864:
1. Large screen LCD12864 Controller
2. Comes with the encoder, can realize the parameter adjustment, and the document choice printing!
3. Ramps plug and play, but need to modify the firmware to support.
Green A4988 stepper motor driver:
1.A simple steps and direction control interface.
2.Six different steps resolutions: full step, half step, 1/4-step, 1/8-step, 1/16-step, 1/32-step.
3.CAN interface directly with 3.3 V and 5 V systems.
4.Over-temperature thermal shutdown, over-current shutdown, under-voltage lockout.
5.Short to ground short circuit load protection.
Endstop Mechanical Limit Switches:
1.Red line connecting VCC (ramps of +)
2.Connect the black wire GND (ramps of -)
3.Green Line connection SIGNAL (ramps in s)
tips: Under normal circumstances, the system must be configured to at least three mechanical switches.
