ULN2003A Stepper Motor Driver Module
350.00Br- Driver Chip ULN2003
- Input voltage 5 to 12V (Separate PSU)
- Max Current 1A
- This ULN2003 Stepper Motor Driver Board is a breakout board made to work with Arduino to power small stepper motors like the 28BYJ-48, and operates on a relatively low 5 to 12V DC at 1A.
- It is controlled via 4 pins and can connect directly to the 3, 4, 5 and 6 pins on a board like the Arduino UNO.
- This breakout board has four step indicator LED’s to indicate which coil is being powered, and an onboard on/off jumper to quickly set the board to on or off status before plugging in the power.
- This breakout board typically draws more current than a standard Arduino can supply, so if you are using this board in conjunction with an Arduino Board, be sure to use a separate power supply at 1A. This will ensure that this board doesn’t damage the Arduino or other components, and that the stepper motor will be able to draw more than enough power to work at optimal order.

ULN2003A Stepper Motor Driver
100.00Br- ULN2003 IC is one of the most commonly used Motor driver IC generally used when we need to drive high current loads using digital logic circuits like Op-maps, Timers, Gates, Arduino, PIC, ARM etc.
- Contains 7 high-voltage and high current Darlington pairs
- Each pair is rated for 50V and 500mA
- Input pins can be triggered by 5V
- All seven Output pins can be connected to gather to drive loads up to (7×500mA) ~3.5A.
- Can be directly controlled by logic devices like Digital Gates, Arduino, PIC etc
-
RAMPS 1.4 board
1,250.00Br- This board is mainly a 12V board and can be modified to work at 24V.
- RAMPS interfaces an Arduino Mega with the powerful Arduino MEGA platform and has plenty room for expansion.
- Ramps is a driver board designed for 3D printer, based on platform (firmware) Repap.
- It not only drivers four steppers so you can design many types of machines based on it, like CNC, and as a mature platform specially for 3D printer, it can also drive extruder, fans, temperature sensors, SD card, etc.
- The RAMPS 1.4 board is an upgrade to v1.3 as it now uses surface mount LEDs, resistors, and capacitors
- The modular design includes plug in stepper drivers and extruder control electronics on an Arduino MEGA shield for easy service, part replacement, upgrade-ability and expansion.
- Additionally, a number of Arduino expansion boards can be added to the system as long as the main RAMPS board is kept to the top of the stack.
- Six different resolutions: full step, half step, 1/4-step,1/8-step,1/16-step,1/32-step.
