RC Interface

Compare Pololu Simple Motor Controllers

The Pololu Simple Motor Controllers make basic control of brushed DC motors easy. Our most versatile and configurable motor controllers yet span a wide range of power levels and offer four interface modes: USB, TTL serial, analog voltage, and hobby radio control (RC).

Compare Pololu Jrk Motor Controllers with Feedback

The jrk motor controllers are highly configurable brushed DC motor controllers that can be used as an open-loop speed control or for closed-loop speed or position control. They support four interface modes: USB, TTL serial, analog voltage, and hobby radio control (RC).

Compare Pololu TReX Dual Motor Controllers

The TReX blends RC, analog, and serial inputs for a powerful motor control solution. The TReX will work right out of the box as an electronic speed control (ESC), but its ability to seamlessly transition between RC/analog and serial control makes it capable of so much more!

Compare RoboClaw Motor Controllers

The RoboClaw motor controllers from Orion Robotics can control a pair of brushed DC motors using serial, RC, or analog inputs. Integrated dual quadrature decoders make it easy to create a closed-loop speed control system.

Pololu RC Servo Multiplexer 4 Channel (assembled)

This compact device serves as a four-channel multiplexer of hobby radio control pulses, allowing easy switching between two independent signal sources. A fifth channel selects whether the output is from the master or the slave source: a pulse width below the threshold selects the master channels, while a longer pulse width selects the slave channels. This version comes with header pins soldered in.

Pololu RC Servo Multiplexer 4 Channel (partial kit)

This compact device serves as a four-channel multiplexer of hobby radio control pulses, allowing easy switching between two independent signal sources. A fifth channel selects whether the output is from the master or the slave source: a pulse width below the threshold selects the master channels, while a longer pulse width selects the slave channels. This version is a partial kit.

Pololu RC Switch with Digital Output

This tiny board converts hobby radio control pulses to digital on/off signals for use in RC switch and simple RC adapter applications. One output indicates the presence of a valid RC signal (10-100 Hz pulse rate, 0.5-2.5 ms pulse width), and the other output indicates whether the pulse width is above or below the 1.6 ms threshold (with ±0.1 ms hysteresis).

Pololu RC Switch with Small Low-Side MOSFET

This tiny board converts hobby radio control pulses to digital on/off signals for use in RC switch and simple RC adapter applications. One output indicates the presence of a valid RC signal (10-100 Hz pulse rate, 0.5-2.5 ms pulse width), and the other output indicates whether the pulse width is above or below the 1.6 ms threshold (with ±0.1 ms hysteresis). An integrated small, low-side MOSFET can be used to drive small loads (up to around 3 A), such as a relay, when the switch is on.

Pololu RC Switch with Medium Low-Side MOSFET

This compact board converts hobby radio control pulses to digital on/off signals for use in RC switch and simple RC adapter applications. One output indicates the presence of a valid RC signal (10-100 Hz pulse rate, 0.5-2.5 ms pulse width), and the other output indicates whether the pulse width is above or below the 1.6 ms threshold (with ±0.1 ms hysteresis). An integrated medium, low-side MOSFET can be used to drive moderate loads (up to around 15 A), such as a relay, when the switch is on.

Pololu SMC04 High-Power Motor Controller w/Feedback

A high-power version of our 3-Amp motor controller, the SMCO4 has the same convenient interfaces (serial, hobby RC pulse, or analog) and improved (10-bit) closed-loop PID control of motor speed or position, all with a more powerful motor driver that can handle higher-current motors.
