A 20x15 mm knob with an internal diameter of 6 mm. For mounting on a potentiometer or rotary encoder

Wireless PS2 controller included with the receiver. It has a range of approx. 8 m and is powered by two AAA batteries. Communication via the SPI interface

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. Pololu 5357

A switching converter that regulates 9V from an input range of 2.6V to 20V. It offers high efficiency of 70-95% and the ability to operate with a continuous input current of up to 900mA and a peak current limit of 2.2A. With a switching frequency of 1.6MHz and a power-saving mode, it is suitable for both high-performance and low-power applications. Pololu 5584

A 16-bit DAC converter module designed to work with M5Stack sets. It enables the conversion of analog signals into a digital signal. M5Stack ADC Unit

Micro SD 128GB class 10 card with Linux Raspberry Pi OS for RPi (old Raspbian)

Pololu 5656 is a breakout board for JST PH and SH 5-pin connectors, allowing easy connection of wires to systems with a 2.54 mm pitch. With support for both connector standards and mounting holes, it is well-suited for projects requiring stable installation and five-channel signal connections.

I2C-UART converter module with two UART output interfaces. Configuration of I2C addresses allows you to connect up to 4 such modules to one controller, which means extending the board\'s capabilities by 8 UART interfaces. DFRobot DFR0627

Pololu 5653 is a JST PH and SH 3-pin connector adapter with side-entry and top-entry outputs, enabling convenient integration with devices based on a 2.54 mm pitch. Designed for projects requiring three channels of signal or power transmission.

ARM Cortex-M3 CPU, 1MB Flash, 96kB RAM, USB, CAN, 5xUART, 2xI2C, 3xSPI, ADC, DAC, STM, LQFP144, RoHS

A switch for e-textile projects that allows you to easily turn circuits on and off with a single click. Thanks to its latching mechanism, it works like a typical switch – one press turns on the power, and another cuts it off. Equipped with large "IN" and "OUT" contact pads, it allows for convenient sewing of conductive thread and quick connection of components such as LEDs or buzzers. Kitronik 2753
