This unit comes with two HG7881 Motor Driver boards integrated onto on tiny chip. Using these chips you get a dual channel stepper driver board that can draw individually 800mA and operate from 2.5v to 12v. Send controls from your microcontroller from 3.3v to 5v digital signal lines from the male header pins. The motors run from PWM Signal, you can adjust the duty cycle to modify the speed.

This small breakout board couples an Electret microphone (100Hz–10kHz) with a 60x mic preamplifier to amplify the sounds of voice, claps, door knocks or any sounds loud enough to be picked up by a microcontroller’s analog-to-digital converter. Each breakout comes fully assembled and works from 2.7V up to 5.5V.

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. This module is compatible with all of the dual-shaft micro metal gearmotors we carry, including the HPCB versions.

Add quadrature encoders to your LP, MP, or HP micro metal gearmotors (extended back shaft version required) with this kit consisting of two sensor boards, two 3-tooth encoder wheels, and two 5-tooth encoder wheels. The installed system does not exceed the 12 mm × 10 mm cross section of the motors and extends only 5 mm beyond the plastic motor end cap. The 3-tooth wheel provides 12 counts per revolution; using the 5-tooth wheel yields 20 counts per revolution. This version is intended for use at 5 V.

This passive buzzer will produce audio only when a AC signal is supplied to the device. When you apply a DC voltage, the buzzer will not generate a tone since it will require a sinusoidal wave. You can achieve this buy supply either a sine wave from a function generator or create PWM waves using a microcontroller or 555 timer. If you are looking for buzzers that make noise when a DC signal is supplied we highly recommend looking for active buzzers.
