00:00Okay, so if you're building a speaker or fixing up an old stereo and you want Bluetooth for less
00:04than the price of a coffee, you're in the right place. I went through the listings,
00:09checked the sales numbers, and pulled the 5 best Bluetooth digital power amplifier boards under
00:13$10.81. Some of these are stupidly cheap and still have thousands of happy buyers,
00:19so let's get into it. First up, the cheapest one here, and honestly the most popular,
00:25a 5W mono Bluetooth amp for just $1.55, with over 4,800 sold and a 4.7 rating.
00:32This little board runs on anything from 3.5 to 5 volts, so a phone charger or a USB power
00:38bank will
00:39do it. It's Bluetooth 5.4, it does TWS pairing, and it has a 3.5mm AUX input if you
00:46want a plug-in
00:47directly. 5W mono is perfect for a single small speaker, a little gift box build, or the DIY
00:53project you've been putting off. At $1.55, it's basically an impulse buy, and it works.
01:00Next, the one with the best reviews, a 10W stereo board for $6.52, rated 4.9 with more than
01:074,500
01:08sold. This one gives you two channels at 5 watts each, Bluetooth 5.0, and it's clearly built with
01:15car audio in mind. But it also does FM radio, plays from a TF card or USB stick, and even
01:21handles
01:21hands-free calls. So you've got Bluetooth, radio, and local files all in one board.
01:28If you want a proper stereo sound and you want it to just work, this is the safest pick on
01:32the list.
01:34Then there's the 6W board at $4.50, sitting right in the middle price-wise, with 4.6 stars and
01:40about
01:404,500 sold. The thing that sets this one apart is the microphone. It's got a mic input plus USB
01:48recording, so it's not just a player, it can actually record. Add FM radio, AUX, and hands-free
01:55audio, and you've got a cheap little hub for a car or a homemade speaker. If you want to mess
02:00around
02:00with recording or karaoke-style stuff on a tiny budget, $4.50 is nothing. Now, if you need real
02:07power, this is the one, a stereo board for $7.86 with two channels at 40 watts each, 80 watts
02:13total,
02:144.8 stars, and over 4,500 sold. This runs on 12 volts, so think car battery or a proper
02:21power supply.
02:22Bluetooth 5.0, FM radio, TF card, USB, mic input, recording, call handling, it's all there.
02:30This is the board you buy when you're driving actual bookshelf or car speakers, not tiny ones.
02:36Under $8 for 80 watts is genuinely hard to beat.
02:40Last one, and it's a different kind of board, so listen close.
02:44This is the VHM314 wireless audio receiver for $3.37, 4.7 stars, roughly 4,400 sold.
02:53Important thing here, it's a receiver, not an amplifier. It has no built-in amp, so it takes
02:59Bluetooth audio and sends it out through a 3.5mm jack or into your own amplifier.
03:05It runs on 5 volts over micro USB, and it's tiny. So if you already have an amp or a
03:11powered
03:11speaker and it just isn't wireless, this is the cheapest, cleanest way to fix that.
03:16Three bucks and you're done.
03:19So there you go. Links for all five are in the description below,
