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

Comfortable & well-fitting, but some differences in stiffness between batches
Size: Medium, Color: Black/Deep Blue/Deep Grey/Heather Grey
I've basically been exclusively buying these since I've discovered them. Super-comfortable and maintain their shape for a long time, but I've noticed from buying it multiple times that sometimes the pouch area has stiffer texture and more support than other times (when it's loose & stretchy like the rest of it). I wish I could specify receiving the more-supported ones because they tend to produce less....how to say, knocking the boys around.

Look great, feel great
Size: Large, Color: Black
These feel great and fit well. With most briefs I tend to the trouble either keeping the front in or not having the back cover everything but these do both things and are very soft. They also look great, even on body types not in the promo picture. They are a great set of briefs and have held up so far and I got mine a little around a year ago and wear them often.

Comfortable, but run big
Size: Small, Color: Red/Orange/Yellow/Blue
I'm a small guy and I purchased size small. The underwear are not bad. Great if you're a bigger guy or if you have a really big butt. If you're on the smaller side or skinnier though they'll fit a little loose. My butt is pretty big, but it doesn't fill out the back completely. Very comfortable though and the waist fits fine. Just a big backside. They don't ride up and so far they're durable. No fading in color and the material holds strong after many wears and washes.
