The 20D mm line of brushed DC gearmotors are available in three different gear ratios, all of which have the same dimensions except for the length of the gearbox. The gearmotor face plate has two mounting holes threaded for M2.5 screws,...

These black plastic wheels press-fit onto the 3mm D shafts on many of our motors, including our micro metal gearmotors and our mini plastic gearmotors , to make a nice drive solution for small robots. The wheels have silicone tires and...

The Pololu A-Star 32U4 Micro is a general-purpose programmable module based on Atmel’s ATmega32U4 AVR microcontroller, which has 32 KB of flash program memory, 2.5 KB of RAM, and built-in USB functionality. Onboard features of the A-Star...

This force-sensing linear potentiometer (FSLP) from Interlink Electronics is a passive component with internal resistances that independently change in response to the location and magnitude of an applied force. This allows a...

This force-sensing resistor (FSR) from Interlink Electronics is a passive component that acts as a variable resistor, with resistance decreasing in response to increasing applied force, which makes it easy to add a touch interface to...

This current sensor is a carrier board or breakout board for Allegro’s ACS714LLCTR-05B-T Hall effect-based linear current sensor; we therefore recommend careful reading of the ACS714 datasheet (678k pdf) before using this product. The...

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...

These tiny, high-torque gearmotors have the highest gear ratio of any motor we sell, which makes them a great choice for applications that require extremely low motor speeds. With no load, the 1000:1 micro metal gearmotor HP output shaft...

These small, two-pin, SPST momentary pushbuttons are intended for mounting to PCBs, but they can also be plugged into standard 0.1" breadboards as shown in the picture to the right. We use them as reset buttons and user pushbuttons in...

These two-pin housings work with our wires with pre-crimped terminals to let you quickly make custom cables that mate with various 0.1"-spaced connectors, including male or female headers and solderless breadboards. They are sold in...
