Pololu Micro Maestro 1351 in kit version enables precise and flexible control of servos and sensors from a PC or microcontroller. Thanks to its ability to operate autonomously and function as a USB–TTL interface, it is used in motion control systems, animatronic projects, and interactive systems responding to external stimuli.

An interactive addition to the BBC micro:bit that lets you create music using 15 touchpads that function like piano keys. The module has a built-in amplifier and speaker, so it doesn\'t require additional audio equipment. Powered via micro USB, it automatically supplies power to the micro:bit, simplifying operation. The keys can perform musical or control functions, making the :KLEF Piano ideal for educational, creative, and hobby projects. Kitronik 5631

Pololu 2834

A compact servo controller based on the PCA9685 chip, allowing simultaneous control of up to 16 RC servos. The board features a built-in Edge Connector for direct connection to the micro:bit and Link-compatible pads for easy integration with other modules. Power can be supplied via the terminal block or servo connectors, and a built-in switch and LED simplify operation. The controller provides a stabilized 3.3V output for the micro:bit and additional devices, making it a perfect central module in your project. Kitronik 5694

WIFI-LPT100 Eval Kit module enables UART data transmission via WiFi, ultra low power consumption, encrypted communication

The TTL TO RS485 (C) module enables the conversion of TTL serial signals to differential RS485 while maintaining high noise immunity and galvanic isolation. With its compact design and built-in ESD and surge protection, it is well-suited for automation systems, IoT, industrial applications, and distributed communication—especially in high-interference environments.

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.)

Module with FM receiver, with its help it is possible to receive radio waves broadcast in the FM band (frequency 50-115MHz). The module has been equipped with a 3,5mm jack socket, through which you can connect headphones. The module has a connector in accordance with the Grove standard. Seeed Studio 107020006

High-quality digital-to-analog converter that allows for pure stereo audio playback without the need for I2C configuration or the MCLK pin. It supports I2S signals (BCLK, WSEL, DIN) and audio formats up to 32 bits and 384 kHz, providing an excellent signal-to-noise ratio (110 dB). Audio output is available via a 3.5 mm jack or on-board pads, and the module works best as a line output to amplifiers and audio systems. Adafruit 6251

Digital audio amplifier dedicated to woofers. It has one channel with a power of 50 W each and can work with speakers from 4 to 8 Ω. It is powered with the voltage from 8 to 25 V

Mini Maestro 12 in kit version is a multifunctional controller for controlling servos, reading sensors, and executing motion sequences without a computer. Excellent for use in robotics, animatronics, and interactive systems, it enables flexible motion control and peripheral management from a PC or microcontroller.

With this smart arduino digital servo shield and Dynamixel AX series servos, It\'s quite easy for you to drive multi servos with daisy chain connection with an Arduino board  such as Arduino Uno, and build your robotic dog, hexapod with powerful servos. DRI0027
