SparkFun Inventor’s Kit (for Arduino Uno) – V3.2

via Pololu - New Products

The SparkFun Inventor’s Kit has everything you need to construct a variety of circuits that will teach you how to use an Arduino Uno to read sensors, display information on an LCD, drive motors, and more. No previous programming or electronics experience is necessary, which makes this a great way for beginners to get started with embedded systems. Version 3.2 adds a new Simon Says circuit with all the LEDs and tactile buttons needed to complete it.

Stepper Motor with 38cm Lead Screw: Bipolar, 200 Steps/Rev, 42×38mm, 2.8V, 1.7 A/Phase

via Pololu - New Products

This NEMA 17-size hybrid bipolar stepping motor has an integrated 38 cm (15″) threaded rod as its output shaft, turning it into a linear actuator capable of precision open-loop positioning. The included traveling nut has four mounting holes and moves 40 µm (1.6 mil) per full step; finer resolution can be achieved with microstepping. The stepper motor has a 1.8° step angle (200 steps/revolution) and each phase draws 1.7 A at 2.8 V, allowing for a holding torque of 3.7 kg-cm (51 oz-in).

This miniature, high-torque gearmotor has a 986.41:1 gearbox, making it a great choice for applications requiring fine control at very low speeds. These units have a 0.365"-long, 3 mm-diameter D-shaped output shaft. This version also has a 4.5 x 1 mm extended motor shaft.

Key specs at 6 V: 32 RPM and 70 mA free-run, 125 oz-in (9 kg-cm) and 1.6 A stall. (Note: stall torque and current specifications are theoretical values; stalling the motor will damage the gearbox.)

iMAX-B6AC V2 Balance Charger and Discharger

via Pololu - New Products

The SKYRC iMAX-B6AC V2 can charge and discharge NiMH, NiCd, Pb, LiPo, Li-ion, and LiFe batteries with individual cell balancing for up to 6 lithium cells. It features a built-in adapter that can be powered from 100–240 VAC, or it can alternatively be powered via an 11–18 VDC input. With its versatile charging capabilities, PC control software, and advanced features like input power monitoring, delta-peak sensitivity, cyclic charging and discharging, and more, the iMAX-B6AC V2 is a great addition to the workbench of any RC, DIY, or robot enthusiast.

99:1 Metal Gearmotor 25Dx54L mm HP with 48 CPR Encoder

via Pololu - New Products

This cylindrical, 2.62" x 0.98" x 0.98" gearmotor uses a brushed DC motor with extra-strong magnets and a 98.78:1 metal gearbox to deliver a lot of power in a relatively small package. It has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 4741 counts per revolution of the gearbox’s output shaft. These units have a 0.315"-long, 4 mm-diameter D-shaped output shaft. We also carry a version of this gearmotor without an encoder.

Key specs at 6 V: 100 RPM and 450 mA free-run, 160 oz-in (11.5 kg-cm) and 6 A stall.

4.4:1 Metal Gearmotor 25Dx48L mm HP with 48 CPR Encoder

via Pololu - New Products

This cylindrical, 2.38" x 0.98" x 0.98" gearmotor uses a brushed DC motor with extra-strong magnets and a 4.4:1 metal gearbox to deliver a lot of power in a relatively small package. It has an integrated 48 CPR quadrature encoder on the motor shaft, which provides 211.2 counts per revolution of the gearbox’s output shaft. These units have a 0.315"-long, 4 mm-diameter D-shaped output shaft. We also carry a version of this gearmotor without an encoder.

Key specs at 6 V: 2220 RPM and 450 mA free-run, 8 oz-in (0.6 kg-cm) and 6 A stall.
