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...

Motor Connections These wheels are designed to press-fit securely onto the 3mm D output shafts on many of our gearmotors, including our micro metal gearmotors and our mini plastic gearmotors. They also work with our 35:1 and 115:1 15.5D...

The TB6612FNG (308k pdf) is a great dual motor driver that is perfect for interfacing two small DC motors such as our micro metal gearmotors to a microcontroller, and it can also be used to control a single bipolar stepper motor. The...

This #2-56, pan-head screw is 1" long. It is made from steel, is zinc-plated, and comes in packs of 25. Dimensions · Length: 1.00 in General Specifications · Threaded type: 2-56

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...
