This black anodized aluminum bracket lets you securely mount typical NEMA 17-size stepper motors to your project. The bracket features several slots and holes for a wide variety of mounting solutions, and four M3×6mm screws are included for securing the motor to the bracket. Pololu 2266

Pololu 4813 is a set of two JST SH 3-pin side-entry adapters that facilitate connecting wires to breadboards and prototype circuits. Thanks to the side-entry wire insertion, the modules are suitable for projects with limited space and requiring organized cable routing.

Allegro\'s TMR sensor module enables precise, non-contact current measurement without breaking the circuit. It offers high sensitivity, low power consumption, an analog output proportional to the magnetic field, and a threshold detection (FLAG) function. Its compact design, AC/DC support, and easy installation make it ideal for energy-efficient and safe current monitoring systems. Pololu 5355

This item is a pair of motor-holding clips for the Romi chassis in white. These clips snap into the main Romi base plate, and then the motors snap into the clips. It is included as part of the white Romi Chassis Kit.

These lightweight aluminum brackets make it easy to mount and integrate the Sharp GP2Y0A02, GP2Y0A21, and GP2Y0A41 Distance Sensors into your project. The brackets are strong enough to hold their position, but they can also be bent by hand to different angles if the application calls for it.

These aluminum gearmotor brackets let you securely mount our larger Pololu plastic gearmotors (228:1 offset, 120:1 offset, 200:1 90-degree, and 120:1 90-degree) to your project. These brackets are sold in pairs, and each bracket comes with two 1″ long and two 0.75″ long #2-56 screws for securing different size motors.

This shield allows you to interface Wixel wireless modules to your Arduino (and other compatible products), enabling simple wireless programming, debugging, and control using standard Arduino software. Pololu 2513

This gearmotor is a miniature high-power, 12 V brushed DC motor with long-life carbon brushes and a 75.81:1 metal gearbox. It has a cross section of 10 × 12 mm, and the D-shaped gearbox output shaft is 9 mm long and 3 mm in diameter.

The controller enables to supply the motors with voltage in the range of 10-47V and power consumption in continuous operation of 1.7A (4.5A peak) for each channel in dual or 3.4A mode (9A peak) in single channel mode. Pololu 2999

Pololu 5651 is an adapter that enables integration of JST PH and SH wires with circuits using a 2.54 mm pitch. Thanks to its compact design and the side-entry PH connector, it is suitable for projects with limited space and where wires need to be routed parallel to the PCB.

Motor with 20 mm diameter and 44 mm length, 156:1 metal gear, 6 V operating voltage, 0.15 A to 2.9 A power consumption, 91 RPM speed and 7.9 kg*cm maximum torque. Pololu 3456

This power distribution board is designed specifically for the Romi chassis as a convenient way to access the chassis’s battery power and pass that on the rest of the electronics that make up your robot. Pololu 3541

The S9V11F3S5C3 switching step-up/step-down regulator efficiently produces a fixed 3.3 V (default) or 5 V (selectable) output whether it is higher or lower than the input voltage, which can range from 3 V to 16 V. The regulator also has fixed 3.3 V low-voltage cutoff with hysteresis that can be used to prevent battery over-discharge.

Pololu 5650 is a JST PH and SH 2-pin connector adapter designed for integration with prototyping boards and modules with a 2.54 mm pitch. It allows conversion between JST PH and SH standards and enables quick wire connections in power and communication projects.
