Module with 4 QTR type optocoupler with RC (digital) output. The module operates from 2.9 V to 5.5 V, detects objects at a distance of up to 40 mm. The sensor will be used in projects that require detection of changes in the ground, e.g. in linefollower robots. Pololu 4144

A small, low-power motor with a 5:1 metal gear, 6 V operating voltage, 0.02 A to 0.36 A power consumption, 2500 RPM speed and a maximum torque of 0.05 kg * cm. Pololu 1100

This step-down converter module allows you to reduce the voltage from 3.5-60V to a stable 3.3V at a current of up to 12A. Its high efficiency of up to 95% and low power losses make it ideal for applications requiring high current and stable power. The device features built-in overcurrent, thermal, and reverse connection protection, as well as a soft-start function and a Power Good indication. Pololu 5670

This gearmotor is a miniature medium-power, 6 V brushed DC motor with a 297.92:1 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.

Tamiya 70188 Mini Motor Gearbox (8-Speed) Kit

DRV8825 Stepper Motor Driver Carrier with male header pins installed, so no soldering is required to use it with an appropriate 16-pin socket or solderless breadboard. Pololu 2982

DC motor driver with voltage 6.5 ... 40V and maximum continuous current 13A. It has the ability to easily implement the feedback loop and numerous control interfaces. Polol 3147

This powerful motor controller makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using our free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC).
