120:1 Mini Plastic Gearmotor, Offset 3mm D-Shaft Output, Extended Motor Shaft

via Pololu - New Products

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. The gearbox has a 0.38″-long, 3 mm-diameter D-shaped output shaft that is offset from but parallel to the motor shaft, and a built-in safety clutch helps protect the gears from excessive loads. This version also has a 4.5×1.5 mm extended motor shaft.

Key specs at 4.5 V: 120 RPM and 80 mA free-run, 20 oz-in (1.4 kg-cm) and 0.8 A stall.

Pololu 5V, 5A Step-Down Voltage Regulator D24V50F5

via Pololu - New Products

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 38 V and efficiently reduces it to 5 V. The board measures only 0.7″ × 0.8″, but it allows a typical continuous output current of up to 5 A. Typical efficiencies of 85% to 95% make this regulator well suited for high-power applications like powering motors or servos. High efficiencies are maintained at light loads by dynamically changing the switching frequency, and an optional shutdown pin enables a low-power state with a current draw of a few hundred microamps.

Translucent Enclosure for Raspberry Pi Model B+

via Pololu - New Products

This protective case is designed specifically for the Raspberry Pi Model B+ (not included). It consists of two pieces, a base and cover, that snap together to securely enclose the board while still allowing access to all of the Raspberry Pi’s ports and header pins. The case has vents in both the cover and base for airflow and a tunnel recess to allow viewing of the operation LEDs.

Magnetic Encoder Disc for Micro Metal Gearmotors, 12 CPR (Bulk)

via Pololu - New Products

These magnetic discs can be used with our micro metal gearmotors with extended motor shafts as part of a quadrature encoder system that offers 12 counts per revolution. Appropriate Hall Effect sensors, such as those in our magnetic encoder pair kits, are required to complete the system. These discs are bulk-packaged and must be ordered in multiples of five. We will package these to order and generally expect orders of up to a few hundred units to ship within a day.

Magnetic Encoder Pair Kit for Micro Metal Gearmotors, 12 CPR, 2.7-18V

via Pololu - New Products

Add quadrature encoders to your micro metal gearmotors (extended back shaft version required) with this kit that uses a magnetic disc and hall effect sensors to provide 12 counts per revolution of the motor shaft. The sensors operate from 2.7 V to 18 V and provide digital outputs that can be connected directly to a microcontroller or other digital circuit.
