Octopus Passive buzzer Brick OBPB01
The Octopus Passive Buzzer Brick is a plug-and-play buzzer module from the Elecfreaks Octopus series. Unlike an active buzzer, the passive design lets you control both tone and volume via PWM, making it ideal for generating melodies, alarms, and sound effects.
Part of the Octopus Electronic Bricks range, it connects directly to Arduino, micro:bit (via Octopus:bit), and other compatible boards using a standard 3-pin analogue interface — no breadboard or soldering required.
Key Features
- Passive Buzzer – PWM-controllable tone and volume
- Plug-and-Play – 3-pin connector (Signal, VCC, GND) for breadboard-free wiring
- Wide Compatibility – Works with Arduino, micro:bit, and other 5 V boards
- Compact Size – 19 × 27 mm
Specifications
- Power Supply: 5 V
- Interface: Analogue (3-pin: S / V / G)
