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.

Great lip balm
I have had chapped lips for most of my adult life. This product has been the first product that I have used, where my lips are not cracked, peeling or dry. There is no smell or taste, very neutral. I had to use the balm frequently in the beginning, now maybe only several times a day. One tube last a long time I highly recommend this lip balm.

Just ok
These are just simply too large to use as chapstick unless you do both top and bottom at the same time ( no thank you). I threw them away. 3 stars because it appears to be a good product, but they got the packaging all wrong to call it chap stick.

Replaced Vaseline - Far superior product
I received this as a gift a few months ago and it's all I use now. I use it on my lips and on my neck wrinkles. Do not leave it in a warm environment, like hot car or pants pockets, it will get very soft. If it does get soft, i just dab it on ranther than rolling/wiping on. Also its best to roll it down when not in use, but not necessary. I used to be addicted to Vaseline products for my lips and this is far superior in many ways.

Not really good as a lip balm
It is way too melty or liquidy when applying. It's like putting oil on your lips. No staying power. I actually ended using it more as a skin moisturizer like a lotion. It's pretty good for that. I haven't even tried taking it with me in my pocket as I think it'll turn to a liquid like coconut oil down here in sunny hot Florida. .
