This add-on board makes it easy to control two high-power DC motors with a Raspberry Pi. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 30 Voperating range and are efficient enough to deliver a continuous 18 A without a heat sink. The drivers offer basic current limiting functionality, and they accept ultrasonic PWM frequencies for quieter operation. 

The 5 V relay module enables safe switching of high-voltage loads via microcontroller logic. Its compact size, mechanical durability, and wide operating conditions make it a versatile choice for automation, lighting control, and DIY electronics projects.
