New product: SparkFun Inventor's Kit - V3.1

We are now carrying the latest version of SparkFun’s Inventor’s Kit (V3.1), which adds a mini screwdriver and replaces the translucent red breadboard from version 3 with an opaque white one that is easier to read. Version 3.1 includes everything else that was part of the previous version, such as the Arduino-compatible RedBoard and all of the additional components needed to build the 15 basic electronic circuits detailed in the guide.

For more information see the SparkFun Inventor’s Kit – V3.1 (with Arduino-Compatible RedBoard) product page.

New product: SparkFun Weather Shield for Arduino

Do you want to build your own weather monitoring station? This weather shield from SparkFun might be what you are looking for. In the form of an Arduino shield, this easy-to-use weather board can measure relative humidity, temperature, barometric pressure, and luminosity.

For more information, see the SparkFun Weather Shield for Arduino product page.

New NEMA 17 stepper motor with optional integrated lead screw

We have added a compact, powerful new NEMA 17-size stepper motor to our wide selection of stepper motors. This 42×38 mm stepper motor is available with a standard 5 mm D-shaft for general-purpose use, but perhaps more exciting is the version with a 28 cm threaded rod, which turns it into a linear actuator capable of precision open-loop position control. This latter version has the stainless steel lead screw built right into the stepper motor, so there is no need to deal with extra hardware such as shaft couplers and set screws, and the copper alloy traveling nut with mounting holes is included. Raise your next project to new heights with the precision (40 µm per full step) and control of a stepper motor!

Please see the product pages for more information:

For other options, you can take a look at our full selection of stepper motors.

New product: Hydra Smart DC Power Supply

The Hydra is a triple-output power converter from CH Robotics designed to make it easier to get the power you need for your next project. The Hydra can quickly give you access to three independent, software-configurable DC output voltages to power your system. The easy-to-use Smart Power Supply Control Software makes it quick and simple to configure and control the Hydra’s outputs from your computer via USB. Bench-top power supplies can be large and bulky, but the Hydra fits in the palm of your hand and can also be configured from a user-programmable microcontroller via serial. This flexibility makes the Hydra a great fit for a large variety of projects, whether you are building an industrial system or a small mobile robot.

For more information, see the Hydra product page.

New products: Universal mounting hubs for 1/4″ shafts

Are you having trouble mounting things to 1/4″ motor shafts? These new versions of our universal mounting hubs fit most 1/4″ shafts, including round and “D” shafts. Similar to our existing universal mounting hubs for 6 mm shafts, these hubs are sold in packs of two and come with two set screws each (4 total) and the appropriate Allen wrench. These new hubs are compatible with our NEMA 23 stepper motors and come in two different versions: the Universal Aluminum Mounting Hub for 1/4″ shaft, with #4-40 mounting holes or the Universal Aluminum Mounting Hub for 1/4″ shaft, with M3 mounting holes.

Controlling a Maestro in C using a Raspberry Pi

Shahmir Javaid tweeted about a tutorial he wrote that describes how he used a Raspberry Pi to control a Maestro servo controller in C. His tutorial documents the steps he took, including setting up the Raspberry Pi for UART, wiring, and programming. The setup is simple, and the code is provided.
