this kit is a good start for starter to build your own 3D printer. basically once you get the electronic parts done. then later it would be more easier to complete the rest parts.

and yes , this is almost all the electronics you need for your 3d projector .

( except motors and extruder hotend )

if you are not sure what you need to complete your 3d printer project .

please feel free to ask .

we not just sell them, we also provide professional after-sales service, so welcome to discuss with us, we will try to do technical support as much as we can.

1) 3D Printer Controller RAMPS 1.4

The RepRap Ardu-compatible 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 Ardu-compatible Mega with the powerful Ardu-compatible MEGA platform and has plenty room for expansion. The modular design includes plug in stepper drivers and extruder control electronics on an Ardu-compatible MEGA shield for easy service, part replacement, upgrade-ability and expansion. Additionally, a number of Ardu expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.


( 1) USB type B receptacle. (2) SD Card add on available. (3) Fits 5 Pololu stepper driver board. (4) LEDs indicate when heater outputs on. (5) Expandable to control other accessories. (6) Heated bed control with additional 11A fuse. (7) Option to connect 2 motors to Z for Prusa Mendel. (8) I2C and SPI pins left available for future expansion. (9) It has provisions for the cartesian robot and extruder. (10) All the Mosfets are hooked into PWM pins for versatility. (11) 3 mosfets for heater / fan outputs and 3 thermistor circuits. (12) Fused at 5A for additional safety and component protection. (13) Pololu boards are on pin header sockets so they can be replaced easily or removed for use in future designs. (14) Servo style connectors are used to connect to the endstops, motors, and leds. These connectors are gold plated, rated for 3A, very compact, and globally available.

2) Ardu Mega 2560 R3

Fully compatible with original Ardu MEGA 2560 R3, with this product, you are able to use all the Ardu open source platform to create or learn interactive objects, it will be a lot of fun while you are creating and learning it, so just get this and start it, we also provide reference pdf files that can help you to improve skills very quickly. after all, time matters, the sooner you can improve your programing skills, the sooner you can create amazing projects! Compared with UNO R3, this is with main Chip ATmega2560, with more I/O Pins, and additional 10 PWM output, of course, the EEPROM is also with larger space.

3) 5 pcs of A4988 StepStick Compatible Stepper Motor Driver Module

A4988 is a complete microstepping motor driver with built-in translator for easy operation. This product is available in full, half, 1/4, 1/8 and 1/16 step modes operate bipolar stepper motors, output drive capacity of up to 35 V and ± 2 A. A4988 includes a fixed off-time current regulator, the regulator in slow or mixed decay modes. A4988 converter is the key to the easy implementation. As long as the “step” input inputting one pulse drives the motor one microstep. There are no phase sequence tables, high frequency control lines, or complex interfaces to program. A4988 interface is very suitable for complex microprocessor is unavailable or is overburdened. In the micro-step operation, A4988 chopping control inside automatically selects the current decay mode (Slow or Mixed). In mixed decay mode, the device is initially set to a fixed downtime in some fast decay, then the rest of the slow decay downtime. Mixed decay current control scheme results in reduced audible motor noise, increased step accuracy, and reduced power consumption. Internal synchronous rectification control circuitry is provided to improve the pulse-width modulation (PWM) operation power consumption. Internal circuit protection includes: thermal shutdown with hysteresis, undervoltage lockout (UVLO), and crossover-current protection. Special power sequencing. A4988 surface mount QFN package (ES), a size of 5 mm × 5 mm, nominal overall package height of 0.90 mm, with an exposed pad for enhanced thermal dissipation. This package is Pb (suffix-T), with 100% matte tin leadframe plating.

LCD 2004 Graphic Smart Display Controller

This full graphic Smart Controller contains a SD-Card reader, an rotary encoder and a 128 x 64 dot matrix LCD display. You can easy connect it to your Ramps board using the “smart adapter” included.
After connecting this panel to your Ramps you don’t need your pc any more, the Smart Controller supplies power for your SD card. Further more all actions like calibration, axes movements can be done by just using the rotary encoder on the Smart Controller. Print your 3D designs without PC, just with a g-code design stored on the SD card.
