ZK‑502L Bluetooth Power Amplifier Board 5.0 Stereo Audio Receiver Channels Digital Audio Amplifier Module for DIY Speakers 5-24V

This is exactly what I needed to interface my BT player into my tractor. Everything is clearly labeled, there is plenty of power, the sound quality is very good, and the bluetooth connectivity is most reliable. All things considered, a very good value.

I had a problem with my first one, I contacted the seller and they responded right away. They sent me a new flashlight even though my original one was almost a year old. Thanks

I was wanting to tinker with something like this to see if it would work to add Bluetooth to my old car. It powered up and has great sound for the size and price. I've only tested it in the house but I'll soon be setting it up in my 53-year-old Buick that only has an AM radio.3/29/2025 Update: I finally wired it up in my dash with a set of stereo speakers. It works very nicely. I wired it to accessory and ignition so it doesn't run the battery down. I used Velcro to attach it to the radio bezel.

Grandson had hooked to speaker and playing music within minutes.

Used this to wire up a portable Bluetooth speaker. Easy to work with and pushes two 6x9’s

For its size a little bit smaller than a credit card thing definitely packs a punch
