Miniature (25x40mm) WiFi b / g / n module with 2.0mm goldpin connection with TCP and UDP protocols operating in standalone and access point mode. The module is equipped with UART and Ethernet interfaces, it is also possible to control GPIO lines. Powered by 3.3V. HF-A11-1

Rotary encoder that enables precise detection of direction and number of revolutions using digital pulses. Equipped with an integrated button, five pins (CLK, DT, SW, VCC, GND) and a metal knob, it is ideal for user interfaces and device control. Thanks to its compatibility with Arduino and Raspberry Pi, durability up to 20,000 cycles and simple integration, it is suitable for educational and DIY projects. KY-040

QTR-8A Reflectance Sensor Array

The LVD2 non-contact voltage tester combines AC voltage detection with a bright LED flashlight in a compact, pen-like design. Designed for commercial and industrial applications, it offers dual signaling – blue light indicates proximity to a voltage source (1-5 inches), while red light signifies direct proximity.
