Ideal Diode Reverse Voltage Protector - reverse voltage and current protection module 4-60V, 20A

DC motor driver that allows you to control the movement of two drives using the I2C interface. Board with connectors for assembly. Pololu 5049

Compact board for controlling RGB and white LED strips, allowing easy connection without the need for soldering. With WS2811F and N-channel FETs, it supports up to 3A of current per channel, making it ideal for high-current LED strips, but does not support RGBW strips. Adafruit 5888

Module with Flash memory W25Q64 with a capacity of 64 Mbit (8 MB). It communicates via the SPI interface. Adafruit 5636

The module protects the load against reverse polarity to -60 V, but does not block reverse current, which is desirable in applications such as motor control. It uses the LM74500-Q1 controller and a MOSFET transistor. Thanks to its low impedance (3 mΩ), it supports currents up to 20 A continuous and 50 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5386

MicroSD card reader module, shield type for Wemos D1
