90×10mm wheel with tire removed. Description 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 plastic gearmotors with 3mm D-shafts. They...

Overview The Pololu A-Star 32U4 Mini boards are general-purpose programmable modules 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. The A-Star...

This board is a compact (0.4″ × 0.9″) carrier for ST’s LPS331AP MEMS absolute pressure sensor, or barometer; we therefore recommend careful reading of the LPS331AP datasheet (453k pdf) before using this product. The LPS331 is a great IC,...

The Pololu P-Star 25K50 Micro is a general-purpose programmable module based on Microchip’s PIC18F25K50 microcontroller, which has 32 KB of flash program memory, 2 KB of RAM, and built-in USB functionality. Onboard features of the P-Star...

This motor driver shield and its corresponding Arduino library make it easy to control a pair of bidirectional, brushed DC motors with an Arduino or Arduino clone. The board features Allegro’s A4990 dual H-bridge motor driver IC, which...

Overview This motor driver shield and its corresponding Arduino library make it easy to control a pair of bidirectional, brushed DC motors with an Arduino or compatible board, such as the A-Star 32U4 Prime. The board features Texas...

These universal mounting hubs are designed to work with most 4 mm diameter shafts, including round shafts, and “D” shafts. Each of the two included hubs has four mounting holes for #4-40 screws (not included), letting you mount custom...

These step-up/step-down regulators take an input voltage from 3 V to 30 V and increase or decrease it as necessary to produce a fixed 5 V, 6 V, 9 V, or 12 V output, depending on the version. They are switching regulators (also called...

These tiny brushed DC gearmotors are intended for use at 6 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range (rotation can start...

Overview Discontinuation notice: These gearmotors have been replaced by functionally identical versions with plastic end caps over the encoders (they use the same motor, encoder, and gearboxes). The protective end caps on the new...

These tiny brushed DC gearmotors are intended for use at 6 V, though in general, these kinds of motors can run at voltages above and below this nominal voltage, so they should comfortably operate in the 3 – 9 V range (rotation can start...

The Tamiya 70100 Track and Wheel Set allows for a large degree of adjustability and creativity in designing your own robot. The set includes a variety of track lengths, sprockets, and wheels that are compatible with multiple Tamiya...
