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

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.

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. 

Linear actuator LACT6P-12V-20 with a 15.2 cm stroke and a 20:1 gear ratio provides a force of 500 N and the ability to monitor position thanks to the built-in potentiometer. Limit switches and a worm drive ensure precise and stable operation in motion control systems.

Black Edition offers adjustable current limiting, over-current and over-temperature protection, and five different microstep resolutions. It operates from 8 V to 35 V and can deliver up to 2 A per coil with sufficient additional cooling. Pololu 2128

Linear actuator LACT8P-12V-20 with a 20.3 cm stroke and a 20:1 gear ratio provides a force of 500 N and a feedback signal for precise position control. Integrated limit switches and a worm drive enable reliable operation in automation and control systems.

Atmel ATmega32U4 microcontroller comes preloaded with an Arduino-compatible bootloader, and the board includes dual motor drivers that can deliver 1.7 A per channel to two brushed DC motors. Pololu 3119

The LSM6DS33 combines a digital 3-axis accelerometer and 3-axis gyroscope into a single package. The sensor provides six independent acceleration and rotation rate readings whose sensitivities can be set in the ranges of ±2 g to ±16 g and ±125°/s to ±2000°/s, available through I²C and SPI interfaces.

66 channel GPS receiver module LS20031. It communicates via the UART TTL interface with a refresh rate of up to 10 Hz. Pololu 2138

The module protects the load against reverse polarity to -60 V, but does not block reverse current, which is desirable in applications such as motor control. It uses the LM74500-Q1 controller and a MOSFET transistor. Thanks to its low impedance (1.5 mΩ), it supports currents up to 25 A continuous and 50 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5387
