LC filter for DC 0-50V 3A power supply

Module with a precise real time clock (RTC) DS3231. It has an integrated crystal resonator and communicates via the I2C interface. DFRobot DFR0819

HAT module with a driver for two DC motors designed for Raspberry Pi. Motors can be powered with the voltage from 6.5 to 30 V and draw a maximum current of up to 18 A. Pololu 3751

Controller with 5 m RGB LED strip (10 LEDs per meter). The LEDs are mounted on a flexible white PCB. Communication is via the Grove interface. Seeed Studio 104020005

This shield makes it easy to control two high-power DC motors with your Arduino or Arduino-compatible board. Its twin discrete MOSFET H-bridges support a wide 6.5 V to 30 V operating range and are efficient enough to deliver a continuous 18 A without a heat sink.
