The LSM6DS33 combines a digital 3-axis accelerometer and 3-axis gyroscope into a single package. The sensor provides six independent acceleration and rotation rate readings whose sensitivities can be set in the ranges of ±2 g to ±16 g and ±125°/s to ±2000°/s, available through I²C and SPI interfaces.

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 small synchronous switching step-down (or buck) regulator takes an input voltage from 4 V to 36 V and efficiently reduces it to 3.3 V. The board measures only 0.7″ × 0.7″ yet delivers a typical continuous output current of up to 2.6 A and features reverse voltage protection.

This is a breakout board for ON Semiconductor’s AMIS-30543 microstepping bipolar stepper motor driver, which features SPI-adjustable current limiting, 11 step modes (from full-step through 1/128-step), back-EMF feedback that can be used for stall detection or optional closed-loop control, and over-current and over-temperature protection. 

Adafruit FeatherWing module with snap relay. It allows you to control high-power components using a microcontroller. It allows switching current to 2A (at 40VAC or 30VDC) and voltage up to 250VAC. Adafruit 2923

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. BOB-12758
