AV to HDMI converter

Step-Down converter D36V50F7 with an output voltage of 7.5 V, an input voltage from 8.3 to 50 V and a maximum output current of 7 A. Pololu 4093

TDA7297 stereo audio digital amplifier module. The system allows you to connect two speakers with an impedance from 4 to 8 Ω and a power of 15 W

The compact (0.4″ × 0.5″) D24V5F1 synchronous buck voltage regulator takes input voltages between 3 V and 36 V and efficiently reduces them to 1.8 V while allowing for a maximum output current of 500 mA. This regulator offers typical efficiencies between 75% and 90%. The pins have a 0.1″ spacing, making this board compatible with standard solderless breadboards and perfboards.

8-channel PoE module with relays allowing you to connect your PC to other electronic circuits via the network. It does not need a separate cable for power and data transmission. It can be controlled via a simple web interface or Telnet. Numato Lab NLRP1001-A

A compact digital rotary encoder module designed for simple and intuitive volume control in arcade and DIY projects. Ready to use without soldering, simply connect it to the "Encoder" port on the Picade Max USB Audio board. In addition to volume control, the encoder offers a mute function when the knob is pressed. Pimoroni PIM770

The module is equipped with eight 10A / 250VAC relays controlled independently via a serial bus (UART) or from a PC (through a microUSB connector). The NO / NC contacts of the relays have been led to the ARK screw terminals. The board recommended for use with Arduino enables the control of eight relays using only two microcontroller lines. ICSTATION ICSE014A

A module with a 24-bit differential ADC NAU7802 optimized for reading strain gauges in a Wheatstone bridge configuration. It offers high precision force or mass measurements. Thanks to the I2C interface, ready-made libraries and screw connectors, it is easy to integrate, especially in mobile and DIY projects. Adafruit 4538

Audio preamplifier module based on RC filters. Equipped with potentiometers to adjust bass, treble and volume level

Zeenko ZK06-BM is a portable, low-noise RF amplifier with battery power, operating in the 10 MHz – 6 GHz band. It offers high gain stability, good overload resistance and full compatibility with spectrum analyzers, including tinySA ULTRA. Particularly recommended for measurement applications and antenna systems.

The Pololu 5423 module provides reliable load control in RC systems with full galvanic isolation. The SPST solid-state relay supports up to 6 A at voltages up to 60 V and is suitable for applications requiring silent operation, durability, and precise control using RC signals. The version without soldered connectors offers flexibility for adaptation to individual projects.

Step-Down converter D36V28F5 with an output voltage of 5 V, an input voltage from 5.3 to 50 V and a maximum output current of 4 A. Pololu 3782

A compact voltage converter module that reduces input voltage from 9.4 to 65 V to a stable 9 V at up to 700 mA. It features high efficiency, low quiescent current (<0.2 mA), and short-circuit and thermal protection, ensuring safe and efficient operation. Its small size and ease of integration make it ideal for mobile devices, battery-powered designs, and systems requiring stable power. Pololu 5436

Pololu 9V Step-Up Voltage Regulator U3V50F9

BMS protection module designed for 10 Li-Ion cells. It has a charging function with balancer option and an over-discharge protection function. Dedicated to an electric bicycle or scooter

The module protects the load against reverse polarity to -60 V and blocks the flow of reverse current to the power supply. It uses the LM74700-Q1 ideal diode controller and a MOSFET transistor. Thanks to its low impedance (10 mΩ), it supports currents up to 10 A continuous and 00 A transient, providing reliable protection and the possibility of easy assembly. Pololu 5382
