Class D digital audio amplifier with Bluetooth 5.0 module. It has two channels with a power of 300 W and can work with 4 Ω speakers. Powered by alternating voltage 230 V

DC motor driver that allows you to control the movement of two drives using the I2C interface. Board with soldered connectors. Pololu 5036

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
