Ding/Dong Door Chime COB PCB ONLY (14pin)
The described electronic assembly consists of two RC (resistor-capacitor) networks, which are pivotal in shaping the audio output tones. The adjustment of component values within these networks allows for fine-tuning of the frequency response, enabling the user to customize the tonal characteristics as per specific requirements.
The circuit is designed to operate at a low standby current of 3V, making it energy-efficient and suitable for battery-powered applications. This is particularly beneficial in portable devices where battery life is a critical factor.
Included in the kit are essential components: a switch for user control, a 1 Watt 8-ohm speaker for audio output, and two AA battery holders that facilitate easy power supply management. The choice of a speaker with an 8-ohm impedance is standard for many audio applications, ensuring compatibility with a wide range of audio amplifiers.
The COB (chip-on-board) component included in the kit is a compact, integrated circuit that simplifies the design by integrating multiple functions into a single package. The specified size of the COB PCB, measuring 16mm by 29mm, indicates a compact footprint, allowing for space-efficient designs in various applications.
Overall, this kit provides a versatile platform for audio tone generation, with the ability to adjust key parameters to meet specific audio needs efficiently.Adjust the component values in the two RC networks to get exactly the tones you want. 3V low stand-by current. Kit includes 1 x switch, 1Watt 8ohm speaker, 2 x AA batery holder, COB and mother board. COB PCB size: 16mm x 29mm. (CPSSG5) 🔗 External reference
