Class D digital audio amplifier with Bluetooth module. It has two channels with a power of 50 W and can work with speakers from 4 to 8 Ω. It is powered with the voltage in the range from 9 to 24 V. NS-01G

This discrete MOSFET H-bridge motor driver enables bidirectional control of one high-power DC brushed motor. The small 1.3×0.8″ board supports a wide 6.5V to 40V voltage range and is efficient enough to deliver a continuous 13A without a heat sink. Driver includes reverse-voltage protection along with basic current sensing and current limiting functionality. Pololu 2992

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36 V and efficiently reduces it to 7.5 V. The board measures only 0.7″ × 0.7″ yet delivers a typical continuous output current of up to 2.4 A and features reverse voltage protection.

The very small step-down 6 V, 2.5 A synchronous inverter can be supplied with voltage up to 36 V, dimensions: 17.8 mm x 17.8 mm. Pololu 2859

The RJ45 splitter allows you to connect two devices to one RJ-45 socket, with the possibility of alternating operation, ensuring protection against electromagnetic interference and connection stability. Lanberg ADS-RJ45-2RJ45-OS
