The audio module with the PCM5100A DAC converter is designed to work with the Raspberry Pi. Pimoroni PIM542

Two-channel ESC controller for brushed motors. It can deliver 40 A and has wires terminated with an XT60 connector

Module with a precise real time clock (RTC) DS3232. It has an integrated crystal resonator, built-in SRAM memory and communicates via the I2C interface. DFRobot DFR0821

The S9V11F3S5CMA switching step-up/step-down regulator efficiently produces a fixed 3.3 V (default) or 5 V (selectable) output whether it is higher or lower than the input voltage, which can range from 2 V to 16 V. (Note: minimum start-up voltage is 3 V, but it operates to 2 V after that.)

Audio player module with Ogg Vorbis, MP3, AAC, WMA and MIDI codec. Equipped with a microSD slot, audio amplifier and LiPo charger. SparkFun DEV-11013

Step-Up converter with an output voltage of 5 to 28 V, an input voltage of 2 to 24 V and a maximum current of 2 A

RGB LED strip driver module dedicated to Arduino boards. It can work with tapes with a supply voltage of up to 12 V and a current consumption of up to 3 A. DFRobot DFR0274

The Step-Down Converter Module converts 0.5V-26V input voltage to 0.8-25V constant, with a maximum output current of 3A, recommended up to 2.3A for long-term use. The conversion efficiency of the device is 96%, and the module size is 22.3mm x 17mm x 4.2mm.

USB - UART converter based on the PL2303 chip. Compatible with voltages of 1.8 V, 2.5 V, 3.3 V and 5 V, it is equipped with a USB type A connector. Waveshare PL2303 USB UART Board (type A) V2

RTC DS1307 real-time clock module and battery CR1220 for the WeMos D1 Mini

USB - UART converter based on the PL2303GS chip. Compatible with 1.8 V, 2.5 V, 3.3 V and 5 V, it is equipped with a micro USB connector. Waveshare PL2303 USB UART Board (micro) V2

This BLDC motor controller, based on the Allegro A89301 chip, enables sensorless control over a wide voltage range from 5.5 V to 48 V and phase current up to 11 A without additional cooling. It supports four control modes: analog voltage, PWM signal, pulse frequency, and via an I²C interface with the ability to configure parameters and save settings to EEPROM. The Field-Oriented Control (FOC) algorithm ensures quiet and efficient operation, while built-in protection protects the system against short circuits, reverse polarity, and undervoltage.
