The Step-Down D24V3F3 Buck Voltage Regulator module gives the output voltage of 3,3V with a wide input voltage range of 4.3-42V and a maximum output current of 300 mA. Pololu 2097

This RC switch converts hobby radio control pulses to digital on/off signals for use in RC switch and simple RC adapter applications. One output indicates the presence of a valid RC signal, and the other indicates whether the switch is active. The activation threshold and direction are configurable, and a safe-start feature reduces the likelihood of unexpected activation. Pololu 2801

DRV8801 Single Brushed DC Motor Driver Carrier

A set of two Pololu wheels measuring 40x7mm in black. Fits D-shaped shaft with a diameter of 3mm. Pololu 1452

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

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 7.5 V. The board measures only 0.7″ × 0.7″, but it allows a typical continuous output current of up to 2.5 A. Typical efficiencies of 85% to 95% make this regulator well suited for powering moderate loads like sensors or small motors.

100:1 Micro Metal Gearmotor MP

Compact current sensor based on TMR technology, enabling precise measurements up to 30 A with minimal energy losses. Thanks to a wide 1 MHz bandwidth, galvanic isolation and interference immunity, it is perfect for applications requiring fast response and high accuracy. Pololu 5305

Pololu 12V Step-Up Voltage Regulator U3V50F12

Step-Up/Step-Down DC-DC converter module. It has an input voltage of 2.8 to 22 V, an output voltage of 12 V and a maximum input of 2.5 A to 3.5 A. Pololu 4984
