Discover the HKM-589971 L293D Motor Drive Expansion Board, a versatile tool designed for Arduino enthusiasts and beginners alike. This motor expansion board transforms your Arduino setup into a powerful platform for robot development and interactive electronics projects.

Whether you are just starting out or looking to enhance your Arduino experience, the HKM-589971 offers a plethora of features that make it both user-friendly and highly functional. With strong driver library support and regular updates, this expansion board is ready to support a range of projects, from simple applications to more complex robotic designs.

Key functionalities include the ability to control up to four bidirectional DC motors and two stepper motors—allowing for precise speed control and rotation angle adjustments. The integration of a 4-way H-bridge powered by the reliable L293D chip provides each bridge with a consistent current of 0.6A (peaking at 1.2A), while maintaining thermal protection.

Wiring is made simple with large terminal connections that accommodate 10-22 AWg cables, ensuring a seamless setup. Additional features like 5V servo motor ports with precision timer support guarantee jitter-free operations. The design is also Arduino-compatible, allowing for quick and efficient development, making it suitable for hobbyists eager to dive into projects.

The package includes one motor drive expansion plate, ready for you to start creating and innovating. The HKM-589971 L293D Motor Drive Expansion Board is an essential addition for anyone looking to expand their Arduino capabilities and bring their electronic projects to life.

Product information:

Application scope: Arduino beginners, Arduino experimental equipment platform, Arduino interactive electronics, Arduino robot, etc.
Features: Many functions, easy to operate, a powerful driver library support and function update.

Product Description:

Arduino is a good introduction to electronic production. With the motor expansion board, Arduino can be a good platform for robot development. This paper introduces a full - function motor expansion board that can drive a variety of simple to slightly complex projects.
This is a commonly used DC motor drive module, using 293D chip small current DC motor drive chip. The pins are made Arduino-compatible, which also facilitates fast Arduino-based development by hobbyists.
2 5V servo motor (steering gear) ports connect to Arduino's high resolution high precision timer - no jitter!
Up to 4 bidirectional DC motors and 4 PWM speed controls (approx. 0.5% resolution)
Up to 2 stepper motors for positive and negative control, single/double step control, staggered or microstep and rotation Angle control.
4-way H-bridge: The L293D chip provides.0.6A (peak 1.2A) current per bridge with thermal power off protection, 4.5V to 36V.
The pull-down resistance ensures that the motor remains in a stopped state when powered on.
Large terminal wiring terminals make wiring easier (10-22 AWg) and power.
With Arduino reset button.
2 large terminal external power terminals to ensure the separation of logic and motor drive power.
Compatible with Mega, Diecimila, & Duemilanove.
A full set of pieces are available for enthusiasts who want to do it themselves.
Download the easy to use Arduino software library for quick project development

Good shelves for the price can be challenging to install correctly
Size: 16 Inch, Color: White, Size: 16 Inch, Color: White
Good quality shelves for the price. Happy with the purchase. They give you assorted hardware to mount each shelf. Wall anchors for masonry or brick and anchors for drywall as well as screws to affix shelf to the wall bracket. The installation was fairly easy but it can be a bit difficult to get the bracket leveled on the wall. The “level” they give you is useless, it is only the tube - not in a housing, so 1 1/2” long. You will need a better level. Basically you place the bracket where you want the shelf to go then make sure it is level and take a pencil to mark the holes. We ended up using a heavier quality wall anchor so only needed 2 anchors instead of the four they send you. Once the bracket is on, slide the shelf onto the bars coming from the bracket and use the 2 set screws to secure it in place. Check for level and if it isn’t you can remove shelf and loosen bracket screws and wiggle the bracket while still attached while retightening screws. We had to re-level one of our shelves this way. Hope this helps and that it makes sense. As for weight capacity I wouldn’t want to put more than a couple of pounds on a shelf. As it is secure, it is hollow inside and too much weight would probably either cause the shelf to sag or damage your wall

Beautiful and sturdy
Size: 24 Inch, Color: White
Excellent quality shelves. All hardware came with them and also the stickers to cover the screws. I also placed a plant on one of the shelves and it’s not leaning and again very nice and secure.
