Overview The Pololu step-up/step-down voltage regulator S10V4F5 is a switching regulator (also called a switched-mode power supply (SMPS) or DC-to-DC converter) with a single-ended primary-inductor converter (SEPIC) topology. It takes an...

The D24V5Fx family of buck (step-down) voltage regulators generates lower output voltages from input voltages as high as 36 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and...

Overview These buck (step-down) voltage regulators generate lower output voltages from input voltages as high as 42 V. They are switching regulators (also called switched-mode power supplies (SMPS) or DC-to-DC converters) and have a...

Overview DRV8801 single brushed DC motor driver carrier with dimensions. Texas Instruments’ DRV8801 is a tiny H-bridge motor driver IC that can be used for bidirectional control of a single brushed DC motor at 8 V to 36 V. It can supply...

This product has been replaced by the newer version of Pololu #3142 Description The jrk 21v3 motor controller is a highly configurable brushed DC motor controller that supports four interface modes: USB, logic-level serial, analog...

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 three-axis accelerometer is a breakout board for Freescale’s MMA7361LC (177k pdf) and MMA7341LC (177k pdf) MEMS (micro-electro-mechanical systems) low-g accelerometers; we therefore recommend careful reading the appropriate...

The 5" robot chassis RRC04A is an 1/8" acrylic chassis that provides a base for our micro metal gearmotors, extended brackets , and 42×19mm wheels . The robot chassis has many mounting holes that let you mount a variety of robot...

The A-Star 32U4 Robot Controller LV with Raspberry Pi Bridge is a programmable module well-suited for robotics applications, designed to work either as an auxiliary controller mounted to a Raspberry Pi or as a standalone control solution...

This ball caster kit includes a two-part black ABS housing, a 1″ diameter POM (also known as acetal or by the brand name Delrin) plastic ball, and three ABS rollers. When assembled, the ball caster is capable of rolling in any direction...

This motor driver board is an add-on for the Raspberry Pi Model B+ , A+, or Pi 2 that lets it easily control a pair of bidirectional, brushed DC motors. The expansion board uses a pair of Freescale MC33926 motor drivers, which operate...
