Miniature high-power motor from the Pololu MP series. Gear motor 250: 1, shaft speed is 90 rpm, torque is 3 kg * cm (0.3 Nm). The motor has an extended shaft which makes it easy to attach the encoder. Pololu 2384

LPS22DF digital barometer module. It enables pressure measurement in the range from 260 to 1260 hPa and communicates via I2C or SPI. Pololu 2898

This gearmotor is a miniature low-power, 6 V brushed DC motor with 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. This version also has a 4.5 × 1 mm extended motor shaft.

This is a breakout board for ON Semiconductor’s AMIS-30543 microstepping bipolar stepper motor driver, which features SPI-adjustable current limiting, 11 step modes (from full-step through 1/128-step), back-EMF feedback that can be used for stall detection or optional closed-loop control, and over-current and over-temperature protection. 

A single-channel DC motor controller with an I2C interface. It is powered from 1.8 V to 22 V and can deliver up to 1.8 A of current. Board with connectors for assembly. Pololu 5075

Small 9 DoF IMU module with 3-axis gyroscope and accelerometer (LSM6DSO) and 3-axis magnetometer (LIS3MDL). It is equipped with an I2C interface, a voltage stabilizer and a logic level converter. Pololu 2862

The GP2Y0A60SZ distance sensor from Sharp offers a wide detection range of 4″ to 60″ (10 cm to 150 cm) and a high update rate of 60 Hz. The distance is indicated by an analog voltage, so only a single analog input is required to interface with the module.

A two-piece aluminum adapter for transmitting wheel drive to motors with a 4mm diameter shaft. Mounting screws and set screws included. Pololu 2672

Step-Up/Step-Down DC-DC converter module. It has an input voltage of 2.8 to 22 V, an output voltage of 3.3 V and a maximum output of 2.5 A to 3.5 A. Pololu 4980

Step-Down converter with input voltage up to 36 V which effectively reduces it to 3.3 V, while maintaining current up to 500 mA. Pololu 2842

The compact (0.4″ × 0.5″) D24V5F15 synchronous buck voltage regulator takes an input voltage of up to 36 V and efficiently reduces it to 15 V while allowing for a maximum output current of 500 mA. Pololu 2847

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″, but it allows a typical continuous output current of up to 5 A. Typical efficiencies of 85% to 95% make this regulator well suited for high-power applications like powering motors or servos.

This gearmotor is a miniature high-power, 6 V brushed DC motor with long-life carbon brushes and a 9.96:1 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.

A two-channel DC motor controller with a I2C interface. It is powered from 1.8 V to 22 V and can deliver up to 1.6 A per motor. Board with connectors for assembly. Pololu 5079

This gearmotor is a miniature high-power, 6 V brushed DC motor with long-life carbon brushes and a 248.98:1 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. This version also has a 4.5 × 1 mm extended motor shaft.

This add-on board enables a Raspberry Pi B+, Pi A+, Pi 2 or Pi 3 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 it easy to get started using our provided software, but the board also exposes most of the driver chips’ I/O pins for more specialized applications. 

DC motor controller that allows the movement of three drives to be controlled via an I2C interface. Kit with connectors for self-assembly. Pololu 5072

Step-Up/Step-Down DC-DC converter module. It has an input voltage of 2.8 to 22 V, an output voltage of 6 V and a maximum output of 2.5 A to 3.5 A. Pololu 4981
