Soft Power Switch Mk2 - power switch with JST 2mm connector

Universal data logger with a built-in web server, four analog inputs, and 24-bit resolution. Digilent 6069-410-007-1

An efficient step-down converter that reduces the input voltage to 3.3 V at a maximum current of 100 mA, offering high efficiency thanks to its low quiescent current (<20 μA). It supports input voltages from 3.3 V to 65 V, has short circuit and overheating protection, making it a reliable and energy-efficient solution. Pololu 5362

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.
