Digital Power Amplifier Board OEP8W / Mono Module / Dual Lithium-PoP Battery 7.2V / 8.4V 10W Differential Speaker

Description

What is the OEP8W? The OEP8W is a digital power amplifier board designed to power high-power speakers. It is compatible with dual-cell LiPo batteries, providing a power supply of 7.2V or 8.4V. Features: Mono digital amplifier board for high-power speakers. Maximum power: 10W (check datasheet) Voltage supply: 7.2V or 8.4V (dual LiPo battery). What is it used for? The OEP8W is ideal for electronic projects that require a powerful speaker powered by batteries. It is suitable for portable devices like drones or alarm systems, making it easy to create effective sound solutions. How to use the OEP8W Digital amplifier OEP8W is ideal for DIY projects that require a powerful battery-powered speaker, such as drones or portable devices. It suits beginner to intermediate maker projects. What do you need? Arduino Uno Power supply 7-8V (LiPo battery) Audio connectors USB cable for Arduino Steps: Connect the OEP8W module power supply to the LiPo battery. Connect the OEP8W module to the Arduino using the appropriate connectors. Connect a 10W differential speaker to the audio output points of the module. Download and upload the provided Arduino sketch to control the amplifier. Test the amplifier with maximum volume to avoid damaging the speakers. Example code: void setup() { pinMode(OUTPUT_PIN, OUTPUT); } void loop() { analogWrite(OUTPUT_PIN, 255); // Set audio output to maximum level. } Mini-project Build a portable alarm system with a light indicator and a OEP8W-powered speaker. The project takes about 30 minutes. Common errors: Reverse power connection. Not testing the correct speaker power before connecting it to the amplifier. Using too strong an audio signal without adjusting the volume. Omitting current surge protection during startup. Recommended accessories: LiPo battery 7.4V 10W differential speaker Audio RCA connectors Arduino Uno Frequently asked questions: How can I adjust the volume? Volume can be adjusted using the analogWrite() function in Arduino. Can it power more than one speaker? Generally, it is designed for a single 10W differential speaker. Check the module specifications for confirmation.
