Posted by Paul on 6 September 2013
Tags: new products

We have expanded our selection of NEMA 23-size stepper motors:

Three of the steppers are in a new 57×56 mm size. We are carrying three voltage/current options: 7.4V, 1 A/phase, 3.6V, 2 A/phase, and 2.5V, 2.8 A/phase.


We have also added a new 4.5V, 2 A/phase option to our selection of larger 57×76 mm stepper motors, at an intermediate point between the 8.6V, 1 A/phase and 3.2V, 2.8 A/phase motors.


We carry one other NEMA 23-size motor in a 57×41mm, 5.7V, 1 A/phase configuration, as well as many other stepper motors.

New product: SparkFun Inventor's Kit - V3 (with RedBoard)

The SparkFun Inventor’s Kit has everything you need to construct a variety of circuits that will teach you how to use an Arduino-compatible RedBoard to read sensors, display information on an LCD, drive motors, and more. No previous programming or electronics experience is necessary, which makes this a great way for beginners to get started with embedded systems. The V3 version includes a RedBoard and detailed instructions for building 15 educational circuits with the kit components.

This replaces the older SparkFun Inventor’s Kit for Arduino with Retail Case.

For more information about the SparkFun Inventor’s Kit, see the product page.

Pololu Wixel with SD Card as USB Mass Storage Device

Pololu Forum user VolAnd, writing from St. Petersburg, Russia, posted about an app that turns a Wixel into a USB SD card reader. The Wixel identifies itself as a mass storage device, and basic read/write operations are working. His goal is to create files with the Wixel that he can then read from a PC. You can read more or get the app from his forum post.

This Wixel app and many others are available in our listing of community-contributed apps on the forum.

Flight Testing of a Surrogate UAV at the National Test Pilot School

This “optionally piloted aircraft” is a Cessna 150 that customer Ryan Olson fitted with an autopilot and remote control system using the Pololu jrk 12v12. It is used for UAV training and development at the National Test Pilot School in Mojave, CA. Ryan’s AUVSI 2012 abstract is available online, and you can see some pictures of the internals below.
