Single-channel DC motor driver with an operating voltage from 10 to 45 V and a continuous current up to 40 A. It can be controlled by an analog signal, PWM, UART, RC or by means of built-in buttons. Cytron MDS40B

SEN-13676

Module with an 11-channel AS7341 sensor that allows the detection of light in various wavelength ranges (color detection). It is equipped with a Gravity connector and communicates via the I2C interface. DFRobot SEN0364

Expansion module with audio and video outputs dedicated to Raspberry Pi Pico boards. It has a VGA output, SD card slot, audio outputs and control buttons. Pimoroni PIM553

Module with a digital temperature and humidity sensor based on the SHTC3 system. Communication takes place via the I2C interface. SparkFun SEN-16467

This small synchronous switching step-down (or buck) regulator takes an input voltage from 4 V to 36 V and efficiently reduces it to 3.3 V. The board measures only 0.7″ × 0.7″ yet delivers a typical continuous output current of up to 2.6 A and features reverse voltage protection.

Module with L3G4200D (3-axis gyroscope with digital output)

This small synchronous switching step-down (or buck) regulator takes an input voltage of up to 36V and efficiently reduces it to 5V. The board measures only 0.7″ × 0.7″ yet delivers a typical continuous output current of up to 2.5A and features reverse voltage protection. Pololu 2858

Module with a light sensor and a proximity sensor up to 5 cm. It allows you to read the illuminance from 0.01 to 64000 lux and communicates via the I2C interface. Pimoroni PIM413

Full/Low Speed 2.5 kV USB Digital Isolator,16-Lead SOIC, Analog Devices, RoHS.
