QTR-3A Reflectance Sensor Array

QTR-3RC Reflectance Sensor Array

A-Star 32U4 Micro

This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its dual robust VNH5019 motor drivers operate from 5.5 to 24 V and can deliver a continuous 12 A (30 A peak) per motor, or a continuous 24 A (60 A peak) to a single motor connected to both channels.

The board allows you to attach cables to the microSD / TF card line. Supply voltage from 2.7 to 3.6 V. Polol 2597

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 two-part aluminum assembly mounts directly to 6 mm diameter motor output shafts like those on our 37D mm gearmotors and allows you to drive most scooter, skateboard, inline skate, and other common wheels that are compatible with popular 608 ball bearings.

The GP2Y0A60SZ offers a wide detection range of 4″ to 60″ (10cm to 150cm) and a high update rate of 60Hz. The distance is indicated by analog voltage - only a single analog input is required to interface with the module. Pololu 2476

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36V and efficiently reduces it to 5V. The board measures only 0.7″ × 0.7″ yet delivers a typical continuous output current of up to 2.5A and features reverse voltage protection. Pololu 2858

This breadboard-compatible module is an alternative to bulky power switches. It uses a small integrated slide switch to control a high-side power MOSFET that can deliver continuous currents up to around 16 A at 4.5 V to 40 V. The board features reverse-voltage protection and also makes it easy to control the MOSFET with an external switch or the digital output of a microcontroller.

This compact, inexpensive plastic gearmotor (brushed DC motor with a 120:1 reduction gearbox) is well suited for use in small robots. While intended for operation at 4.5 V, it should run comfortably in the 3 V to 6 V range.
