D Class Power Audio Board with 6W Linear Amplifier PAM8403 5V CA-8403 Standard Voltage

I’ve been using this Creatall AS21 amplifier for my home theater setup for a month, and it’s been fantastic! The build quality is top-notch—metal construction feels durable and premium. The TPA3255 chip delivers crisp highs, balanced mids, and deep, punchy bass that fills the room without distortion. Bluetooth 5.1 pairs quickly with my phone and smart TV, and the connection stays solid even through walls. I appreciate the multiple input options (AUX/USB/Bluetooth) that let me switch between devices easily. The protection features (overheat, short circuit) give me peace of mind for long-term use. The company’s customer service was responsive when I had questions about wiring, and the sample delivery was fast (arrived in 7 days as promised). For the price, it’s way better than some expensive brands I’ve tried—highly recommend for anyone looking for a reliable, high-performance amplifier!

This 5S BMS board is perfect for my solar lighting battery. It protects against overcharging well, and the voltage monitoring is accurate. It’s kept my battery in great condition.

This multi-S BMS board is fantastic. It handles 100A current smoothly, protects my ternary battery well, and works with 3S/4S/5S setups without adjustments.
