LC filter for DC 0-25V 3A power supply

The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board. COM-13705

Module for recording sounds, which can store recordings up to 20 seconds. The board is equipped with a Grove connector and communicates via a digital interface. Seeed Studio 107020007

Stereo audio isolator based on two transformers. It allows to eliminate noise in the audio path resulting from different ground resistances of the sound source and the receiver. XH-M372

A cable with a built-in converter that increases the voltage from the USB connector to 9 V. It is equipped with a DC Jack 2.1 x 5.5 mm plug

USB-CAN adapter with support for CAN2.0A and CAN2.0B standards. It can work with Windows and Linux systems, including Raspberry Pi and Jetson Nano minicomputers. Waveshare USB-CAN-A

Flexible cable (tape) 50 cm long, used to connect the camera module with Raspberry Pi computers. The tape has 15 wires and a pitch of 1mm

Module with 2 relays SRD-05VDC-SL-C with a load up to 10 A. The board is equipped with a Grove connector and is controlled by a digital signal. Seeed Studio 103020132

Ultrasonic distance sensor MB1030 with a range from 0 to 645 cm. It has an output in the form of a serial interface, analog signal or generates an impulse whose duration is proportional to the measured distance. Pololu 793

Step-Down converter with adjustable output voltage from 1.25 to 36 V, input voltage from 4 to 38 V and maximum current up to 5 A. Board equipped with a voltmeter with display

Industrial RS232 to RS485 converter. It is equipped with digital isolation and is mounted on a DIN rail. Waveshare RS232 TO RS485 (B)

The protection circuit for one Li-Ion cell with a voltage of 3.7 V. It has the function of charging, discharging and over-discharge protection. The cells can be discharged with a continuous current of up to 8 A

This Bluetooth Audio receiver module includes a USB port and TF card slot. With a pre-amp output, you can drive headphones or a 3W speaker directly. You can also add an active power amplifier and connect a loudspeaker. The module supports MP3, WMA, WAV and lossless FLAC audio formats. DFRobot TEL0108

Audio module with DAC, stereo amplifier and display, designed to work with the Raspberry Pi. Pimoroni PIM484

RoboClaw 2x160A Motor Controller is a two-channel DC motor driver, operating voltage: 10.5..60V, maximum continuous current: 120A, easy implementation of feedback loops with PID controller, safety systems. Pololu 3582

The S9V11F5S6CMA switching step-up/step-down regulator efficiently produces a fixed 5 V (default) or 6 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.)

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