This shunt regulator can protect power supplies from voltage spikes generated by motor controllers they are connected to. This version has a precision-adjustable set point (4 V to 35 V) , a shunt resistance of 4.10 ohms , and a total of...

This plastic bracket provides a convenient way to mount standard-size servos with a side flat to a surface. Rear view of Power HD Continuous Rotation Servo AR-3606HB and Solarbotics red servo wheel with Mounting Bracket for Standard-Size...

The A-Star 32U4 Mini SV is a programmable module based on the ATmega32U4 from Microchip (formerly Atmel). Unlike competing products, it has an on-board switching step-down regulator that allows it to be powered efficiently from a 5 V to...

This version of our STSPIN820 Stepper Motor Driver Compact Carrier ships with male header pins installed as shown in the main product picture, so no soldering is required to use it with an appropriate 16-pin socket or solderless...

This breakout board for STMicro’s STSPIN820 microstepping bipolar stepper motor driver offers microstepping down to 1/256-step and a wide operating range of 7 V to 45 V. It can deliver up to approximately 0.9 A per phase continuously...

The Pololu RC switch with Small Low-Side MOSFET can be used with standard hobby radio control systems for radio control switch applications or simple interface applications. Example uses include converting extra RC receiver or servo...

This product consists of a single-pole, double-throw (SPDT) power relay and a control circuit that measures incoming radio control (RC) signals, making it easy to control large, electrically isolated loads in RC systems. Example...

This sensor module has 8 IR LED/phototransistor pairs mounted on a 0.375" pitch, making it a great detector for a line-following robot. Pairs of LEDs are arranged in series to halve current consumption, and a MOSFET allows the LEDs to be...

The six-channel Micro Maestro raises the performance bar for serial servo controllers with features such as a native USB interface and internal scripting control. Whether you want high-performance servo control (0.25μs resolution with...

This ball caster can be used as a replacement 3pi robot part or as a general-purpose ball caster. When mounted through a hole in a chassis that uses our micro metal gearmotors and our 32×7mm wheels , as on the 3pi, this ball caster is...
