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.

Last week we announced the Pololu RC Switch with Relay, the first product in our overhaul of the RC Switch family. Today we released the second new RC Switch product, the Pololu RC Switch with Medium Low-Side MOSFET. This board converts hobby radio control pulses to digital on/off signals and has an integrated medium, low-side MOSFET that allows it to drive moderate loads (up to around 15 A), such as lighting or small actuators.

This product replaces item #1211 and includes valuable new features such as a safe-start mode and user-configurable input direction and threshold.

We are overhauling our RC Switch family of products, starting with a new and long-awaited addition, the Pololu RC Switch with Relay. This RC relay board makes it easy to control large loads within radio control (RC) systems. Here is an example setup with a typical RC receiver controlling the switch:

The Pololu RC Switch with Relay has advanced features not present in earlier RC switch products, including a safe-start mode and configurable input direction and threshold.

In addition to the assembled version shown above, a partial kit is available for specialized applications such as custom connectors or alternative relays:
