Module with 1 optocoupler type QTRXL with RC (digital) output. It is supplied with the voltage from 2.9 to 5.5 V, detects objects at a distance of up to 80 mm. Pololu 4501

1.9inch Touch LCD is a compact IPS display with capacitive touch, designed for projects based on microcontrollers and single-board computers. Thanks to the SPI and I2C interfaces and built-in logic level conversion, it allows easy integration with platforms such as Raspberry Pi, ESP32, STM32, and Arduino.

This powerful motor controller makes closed-loop speed or position (but not both!) control of a brushed DC motor easy, with quick configuration over USB using our free software. It supports five control interfaces: USB, TTL serial, I²C, analog voltage (potentiometer), and hobby radio control (RC).

Force-Sensing Resistor - 1.5" Square

Step-Up/Step-Down DC-DC converter module. It has an input voltage of 2.8 to 22 V, an output voltage of 6 V and a maximum output of 2.5 A to 3.5 A. Pololu 4981

A small USB 2.0 hub that allows you to disable individual devices connected to its USB ports, as well as a visual evaluation of the number of devices enabled. It has a built-in connector for the external power supply, so it can act as an active hub. Cable with a length of 40cm, 4 USB ports

Expander (shield) compatible with Arduino and NUCLEO (STM32) systems, equipped with a Bluetooth 4.1 (BLE) radio module from the SPBTLE-RF family
