We are now carrying the Raspberry Pi Model B, Revision 2.0!

In case you haven’t heard of the Raspberry Pi, it is a popular credit card-sized computer that can run Linux. It was designed by the Raspberry Pi Foundation in order to provide an affordable platform for experimentation and education in computer programming. The Raspberry Pi can be used for many of the things that a normal desktop PC does, including word-processing, spreadsheets, high-definition video, games, and programming. With its 0.1″-spaced GPIO header and small size, the Raspberry Pi also works as a programmable controller in a wide variety of robotics and electronics applications. We have seen a lot of our customers do neat things with the Raspberry Pi, and we have featured several of those projects on this blog.

Our 75:1 HP micro metal gearmotor is now available with an extended motor shaft that works with our recently released optical quadrature encoders. If there are other gear ratios that you would like to see available with extended motor shafts, we would love to hear about it.

For more information on this gearmotor, see the product page. For other options, you can take a look at our full selection of micro metal gearmotors.

When properly modified for continuous rotation, hobby RC servos become an inexpensive, compact, easy-to-use actuator system for robotics projects, and servo manufacturers are increasingly answering the growing demand for such products with servos designed specifically for robots. One example is Power HD’s new AR-3606HB continuous rotation servo, which offers open-loop speed control rather than the closed-loop position control you typically get with a servo. It is the fastest and strongest continuous rotation servo we carry (up to 71 RPM and 93 oz*in of torque), with performance well suited for driving a small robot.

For more information on the AR-3606HB, see the product page. For other options, you can check out our full selection of continuous rotation servos or our entire RC servo category.

USB Mini-B connector breakout board with included optional header pins.

USB Micro-B connector breakout board (older usb04b version) with included optional header pins.

These basic boards conveniently break out the VBUS, GND, D-, D+ and ID pins of USB Mini-B and Micro-B connectors to a set of five 0.1″-spaced pins, making it easy to power your project from a USB port or to add a USB connector to your breadboarded USB microcontroller. The compact USB Mini-B Connector Breakout Board measures 0.55" × 0.85", while the even smaller USB Micro-B Connector Breakout Board measures 0.44" × 0.5" (including the USB connectors).

We are now carrying female 0.1" headers with right-angle pins, in sizes from 1×2 to 1×12. You can view these and other female header products on the category page.

Pololu RC Switch with Digital Output.

Pololu RC Switch with Small Low-Side MOSFET.

With the release of the new RC Switch with Digital Output and the new RC Switch with Small Low-Side MOSFET, our RC switch family overhaul is now complete. These compact modules convert hobby radio control pulses to digital on/off signals for use in RC switch and simple RC adapter applications. These products replace item #752 and item #1210, which have been put on clearance and will be discontinued when the remaining stock is gone.

For more information about these products and the rest of our RC switch family, see our RC Switch category.

The overhaul of our RC switch and RC multiplexer products continues with the new Pololu 4-Channel RC Servo Multiplexer. This compact four-channel multiplexer of hobby radio control pulses allows for easy switching between two independent RC signal sources. An auxiliary channel selects whether master or slave inputs show up on the four output channels. This makes it ideal for applications in which you have two possible control sources and want to be able to switch between them on the fly.

This product replaces items #721 and #722 and includes valuable new features such as user-configurable input direction and threshold.
