The first Raspberry microcontroller with the proprietary RP2040 chip and a dual-core Arm Cortex-M0+, the Foundation's cost-effective yet highly flexible solution. Designed for high performance and with a high degree of digital interfaces. Programming in C/ C++ and MicroPython.

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
