RAMPS 1.4 Controller for 3D Printer with Heatsinks A4988, USB Cable and Jumper Kit

Discover our RAMPS 1.4 board, the cost-effective all-in-one solution designed to pack all the electronics needed for a RepRap printer into a compact form factor. This board serves as a powerful interface between a Mega microcontroller and the MEGA platform, offering numerous expansion possibilities thanks to its modular design. It integrates stepper drivers and an extruder controller that plug directly onto a MEGA shield, simplifying maintenance, parts replacement, upgrades, and system expansion. Furthermore, it is possible to add multiple expansion boards to your configuration, provided you keep the main RAMPS board at the top of the stack. The included Mega microcontroller is a fully functional development board, equipped with 54 digital input/output pins (14 of which can provide PWM output), 16 analog inputs, 4 UART ports (hardware serial ports), and operates with a 16 MHz crystal oscillator. Thanks to its bootloader, you can upload your programs directly via USB, without needing an external programmer. Power can be supplied optionally via the USB port or via an external source using an AC/DC adapter or a battery. Its development environment (IDE) is based on open-source principles, allowing you to download it freely for your projects, teaching, motor control, or creating interactive works. The kit also includes five soldered A4988 stepper motor drivers. Each A4988 driver is a carrier board for the Allegro A4988 DMOS microstepping driver, incorporating a translator and overcurrent protection. It allows you to control a bipolar stepper motor with an output current of up to 2 A per coil.
