Led Matrix 8x8 MAX7219 Soldier

The piezoelectric buzzer has a simple structure in which a ceramic piezoelectric disk is affixed to a vibrating plate. An alternative voltage applied to this element will cause a contraction or diametrical expansion of the element. This feature is used to fold a vibrating plate, which generates sounds. 2x Passive Buzzer 5V features:

- Input voltage: 3V to 12V
- Diameter: 12mm
- Height: 7.5mm
- Pin spacing: 6.5mm
- Impedance: 16 Ohm
- Working frequency: 2 to 5 KHz
- Quantity: 1 unit

WROOM-32 DEVKIT V1 is an ESP32 processor development board with WiFi and Bluetooth (BLE). It is much faster than the ESP8266 processor (NodeMCU and similar), and very easy to use, with 2x15 pins.

Impressive, professional, high-definition camera module. Official product of Raspberry Pi.

The official Raspberry Pi HQ Camera includes a 1/3" (8.5mm) Sony IMX477 sensor with 12.3MPx resolution and up to 50% increased sensitivity of pixels per area, offering greater sensitivity to light.

It is specially designed to work with CS or C-mount interchangeable lenses (CS-C adapter included). It allows you to use both fixed and varifocal lenses, and you can also use other lenses such as M12 lenses by using an M12 to CS mount converter.
