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

We just added bulk stranded hook-up wire in six gauges (20, 22, 24, 26, 28, and 30 AWG) and six colors to our selection of cables and wire. With all the combinations, that’s 36 new options for wiring up your next project! The convenient mini spools are all filled, so the wire lengths range from 40 to 100 feet (12 to 30 meters), depending on thickness.
We have released two new step-up regulators that can boost input voltages as low as 0.5 V. Like the very similar U1V11x line of step-up regulators, these modules automatically switch to a linear down-regulator mode when the input voltage exceeds the output, making them great for powering electronics projects from 1 to 3 NiMH, NiCd, or alkaline cells or from a single lithium-ion cell. These modules do not offer the U1V11x shutdown functionality, which allows them to be much smaller (just 0.35″×0.45″) and a little less expensive ($4.49 each).
These regulators are available with a 3.3 V or 5 V fixed output voltage. For other options, you can take a look at our full selection of step-up voltage regulators, step-down voltage regulators, and step-up/step-down regulators.
We are now selling the motor and encoder portion of three of our metal gearmotors, without a gearbox. The pinion gear on the output shaft works with the gearboxes on the corresponding products, so these can be used as replacement motors or encoders.
Our universal mounting hubs are now available in versions with mounting holes sized for M3 screws (not included). These aluminum hubs allow you to mount custom wheels and mechanisms to 3 mm, 4 mm, 5 mm, and 6 mm shafts. Each set of two hubs includes the required set screws and an Allen wrench for securing the hubs to motor shafts.
We have released a new machined aluminum bracket that lets you securely mount our 37D mm metal gearmotors to your project. The bracket has six holes on its face that line up with the 37D gearbox’s mounting holes, and it has three tapped holes on the bottom. Nine M3 screws are included for securing the bracket to the motor and mounting surface.
Our new QTR-3A and QTR-3RC reflectance sensor arrays pack three IR emitter and receiver (phototransistor) pairs onto a board measuring just 1.25″ × 0.3″ (32 mm × 8 mm). With the sensors mounted on a 0.375″ pitch, these sensor arrays are great for sensing 3/4″ black electrical tape when used as minimal detectors on line-following robots!
The SparkFun Starter Kit for RedBoard is an easy way to get started building entertaining and educational circuits with SparkFun’s RedBoard, an Arduino clone that is compatible with the Uno R3. The kit includes a RedBoard along with various types of sensors and indicators. A downloadable guide features example projects to introduce you to the world of embedded electronics.
