The Pololu micro serial servo controller (SSC) is a very compact solution for controlling up to eightradio control (RC) servos from a computer or microcontroller. The controller measures just 0.91" x 0.91", yet it is one of the most...

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...

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 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...

This programmable module is designed to be the core of a small robot, either as an auxiliary controller atop a Raspberry Pi base or as a complete control solution on its own. Its Atmel ATmega32U4 microcontroller comes preloaded with an...

These universal mounting hubs are designed to work with most 0.250 inch (6.35 mm) shafts, including round shafts and “D” shafts, such as those on our NEMA 23 stepper motors . Each of the two included hubs has four mounting holes for...

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 metal gearmotors...

This current sensor is a carrier board or breakout board for Allegro’s ACS711KEXLT-15AB-T Hall effect-based linear current sensor with overcurrent fault output; we therefore recommend careful reading of the ACS711 datasheet (533k pdf)...

Description These 20 mm long aluminum adapters convert a 6 mm diameter shaft to a 12 mm hex shaft that is compatible with many common hobby RC wheels. The set includes two adapters, two M4 screws for securing wheels to the adapters, four...

This add-on board enables a Raspberry Pi B+, A+, or Pi 2 to drive a pair of brushed DC motors. Its dual MC33926 motor drivers operate from 5 V to 28 V and can deliver a continuous 3 A (5 A peak) per motor. The default pin mappings make...
