DC motor controller that allows the movement of three drives to be controlled via an I2C interface. Pololu 5073

Pololu High-Power Motor Driver 36v20 CS

Miniature, 12V brush DC motor with metal gear and 15.25:1 gear ratio. It has a cross section of 10 × 12 mm, and the D-shaped output shaft with a length of 9 mm and a diameter of 3 mm. Pololu 4786

Module with a digital distance sensor with a range of up to 50 cm. It has a digital output that goes low when an object is detected. Pololu 4067

Step-Down converter D36V50F5 with an output voltage of 5 V, an input voltage from 5.5 to 50 V and a maximum output current of 8 A. Pololu 4091

Female-female cable, 10 cm long, with JST-SH 6-pin plug on both sides. Suitable for micro DC motor encoders with gear. Pololu 4765

The module protects the load against reverse polarity to -60 V and blocks the flow of reverse current to the power supply. It uses the LM74700-Q1 ideal diode 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 5389

A set of two 80x10mm black Pololu wheels. Fits D-shaped shaft with a diameter of 3mm. Pololu 1430

A module that provides a regulated, galvanically isolated power supply. It allows easy changing of the output voltage from 5 V to 3.3 V using the voltage selection pin (VSEL). Galvanic isolation between input and output effectively prevents problems related to ground loops and ground currents, ensuring stability and protection of the system. Pololu 5384

Power HD Micro Servo HD-1600A

Tamiya double gear dedicated to small mobile robots. It is made of plastic modes that can be adjusted to two gears: 58:1 and 203:1. Pololu 61

Step-Up/Step-Down converter module based on the S13V30F5 system, input voltage from 2.8 to 22 V, output voltage 5 V. Current efficiency of the converter 4 A. Pololu 4082
