Description

SparkFun SparkFun AutoDriver - Stepper Motor Driver (v13)The SparkFun AutoDriver board is based on the STMicro L6470 dSPIN stepper motor driver. This powerful chip allows you to control a stepper motor with a voltage from 8 to 45V at 3Arms over an SPI connection. The AutoDriver board has been designed to be easily integrated into a project, even with multiple boards. Just connect your motors and your SPI capable microcontroller and get steppin'!

The SparkFun AutoDriver board is based on the STMicro L6470 dSPIN stepper motor driver. This powerful chip allows you to control a stepper motor with a voltage from 8 to 45V at 3Arms over an SPI connection. The AutoDriver board has been designed to be easily integrated into a project, even with multiple boards. Just connect your motors and your SPI-capable microcontroller and get steppin'!

STMicro’s L6470 is a 3A, 8–45V bipolar stepper motor driver. It has built-in overcurrent detection, undervoltage detection, overtemperature detection, stall detection, a 5-bit ADC, and a switch input that can be used for either user jog control or as a hard stop function. As if that weren’t enough, it also features microstepping support (up to 128 microsteps per full step) and PWM drive voltage limiting. Please keep in mind that the L6470 requires a great deal more configuration and adds software complexity to your system.

Unlike most stepper motor drivers, the dSPIN is controlled over an SPI link. It has an onboard 16MHz oscillator, which allows it to autonomously execute movement commands. That means no more counting steps in your code! It also supports customized acceleration and deceleration profiles to prevent jerky starts and stops. Onboard registers track current speed and location.

This new version of the SparkFun AutoDriver’s hardware is slightly different from the previous revision. It has been modified to make it easier to daisy-chain multiple boards together with simple 10-conductor ribbon cables for data and 6-conductor ribbon cables for control. The library has been updated as well, with more information found in the Hookup Guide below.

The logic supply voltage supports both 3.3V and 5V I/O levels.

Great book, but no new info for a huge Homer fan...
Format: Hardcover
Neat book, but anyone who is a huge Homer fan, like my husband (who the book was for) will not learn anything new - so I am told. Although there is a ton of great info in there about Homer and his friends/everyday life, it's a huge disappointment to hear that he already knows everything in the book. I guess that's a super-fan for you!

To funny
Format: Hardcover
If you’ve seen the show, then the book is just as funny. It takes all of Homer’s “advice” and puts it into a cute book. I have it on my shelf next to my Duff energy drink

Funny and unexpected
Format: Hardcover
I bought this book for my girlfriend who is a big Ralph Wiggum fan. When it arrived, I was shocked to see what a thorough exploration of the character it was. I'm not saying it's all canon in terms of the show, as i saw some complaints that there was stuff in this book that wouldn't make sense to the Ralph character (such as his love for Lisa) due to them "breaking up" in a past episode, but come on, that's a hogwash complaint. The whole point of this book is to entertain, and it does so in spades, so it comes highly recommended. And this is coming from a huge 'The Simpsons' fan himself. Oh, and by the way, my girlfriend loved it, too.
