SKU Type Active : A07009 SKU Type Passive : A18009
Active Buzzer
working voltage 3.3V-5V with fixed bolt holes for easy installation small board PCB size: 3.2cm * 1.3cm When the I / O port is input Low level, buzzer Voice Silahkan kasih trigger ground maka buzzer akan nyala terus menerus (selama ada trigger)
Pin Definition : Vcc : 3.3-5v GND : The Ground I/O : External MCU IO port
Passive Buzzer
No oscillation source,need square wave(frequency 2K-5K ) to drive Untuk menyalakan perlu kasih trigger PWM, kalau cuma GND cuma nyala sebentar lalu mati Work Voltage:3.3-5V PCB Dimension : 3.3cm*1.3cm
Pin Definition : Vcc : 3.3-5v GND : The Ground I/O : I/O Interface of SCM
Sudah ada transistor untuk triggernya, sehingga aman untuk micro controller
