No not necessarily. An ESP32 has two DAC. They are low-bit low-power DACs, but still. If it's enough for your project theres no reason to overengineer it
@@comedyclub333 yeah, working on a project and needing audio from my esp32 and it's been a pain. Then got a max98357a and still just silence. Using the test audio on the sound amp GitHub, but serial is reading the SD card, listed the tracks, for the bitrate info and everything, then says playing and a second later says finished. So sound is proving to be difficult for me, lol. But yeah. In my research, that's where I found the dac is removed from S3. But, esspresif said the S3 has a high frequency pwm which can be used like a dac
It is. The output power and bit depth of the internal DACs is shot, though, so your audio quality will suffer. But it is in pronciple enough to process audio data and play sound.
The Esp32 has 2 dacs so yes you can connect it directly to speaker if its a small one. For those large speakers you would destroy the chip with that load. If you are pushing such huge speakers use a opamp or audio amp to prevent the speakers from killing the chip from power draw. The same can be said for anything else. Use amps or transistors if you intend to drive large loads ( Stuff that use More power than Leds)
Hi, I am using the same code in the video. After installing the library, the code successfully compiles but I hear no audio when I connect the DAC pins to a headphone. Any guidance on how to solve this would be helpful. Thanks!
If you're reading this, please, do not connect any kind of coil directly to esp32, this may damage the board and in worst cases, the USB port of your PC
@@Utkrant_Hingonekaryou can use any audio amplifier, the most common are TDA2003, LM386 PAM8610 TPA3110 you need to use an external voltage source or make a low power class a with a transistor
@@schokodrache3793 dude it's not the reason why I can say this is not because it's a circuit do-it-yourself it is possible because all about coding and programming it looks like you don't know I might not know how to do the coding but I know how the coding work's
Esp32 : bro pls stop pls im dying
😂 that's what I thought too lol
NO U MUST NOT CONNECT SPEAKER DIRECTLY TO THE BOARD! You need to use amplifier
you do not need to. you can.

@@comedyclub333S3 model and higher do not have a DAC anymore :(
@@MikeHarris1984 Oh really? Okay, that's a shame. For most cases the old/standard ESP32 models are sufficient (and cheaper) fortunately.

I doubt that the ESP32 would be that powerful for either the speakers or the audio itself.
The 3.5mm jack can already provide enough power for a pretty loud speaker

the dacs are pretty low resolution so they wouldn’t sound good even on appropriate sized speakers. Better to use an external dac over I2S
@@myriadtechrepair1191 you can use pwm too
Esp is must be in pain cuz of that 4 ohm load💀
how did you get vintage speakers
they are hard to just have lying around
Stunning audio quality 😂
Wait since the transmission is yhrough wifi does that mean it is loseless audio?

I have question how can i reduce the buzzing sound

Esp32 even easily broken by direct connect to small buzzer
*the Bluetooth device is really to pair*
" Bluetooth headphones " ??? 😂 I think that's what you meant haha 🤣
how to blow esp32`s DAC
I want to learn this can anyone guide me
How can we send serial data alog with bluetooth speaker
Code ???
This does not supply an AC voltage for the speakers but a dc voltage
why not use an amplifier instead of abusing the esp32 by directly hooking the speakers?
Ye jo Bluetooth module hai iska link de do bhai koi accha wola or sasta jo 10w +10w 2 speaker chal sake plz bhai
what is the code
vas a quemar la placa en pocos minutos

Speaker ka kya name hai
I’m literally creating a speaker from wire, cones and magnets.
Whats the device which is used to connect external speakers to ??
esp32 - speakers in this video. It is also possible through an external DAC. Here is an example ua-cam.com/video/24pk28oqVQI/v-deo.html
Where you bought those speaker? I need this exact model
I took the speakers from old computer speakers. I can't tell you the model
You cAn get these from any scrap tv
Dont do this people. Good way to destroy your board. Back EMF from inductor (speaker coils)
it's rather insane current draw from 4 Ohm speakers, that's why amplifiers are used
33mW , the not enough to move the paper cone 1/10 h if a millimetre
Tv woofers 👌😭
Bhai kuch to explain karte jo nhi jante aur jaanne ki koshish kar rhe ho unka kia??
This is not fake he needs a amplifier I made this mistake before
Day 126 of shearching the programs that are in that bluetooth thing
Hooking up a 2Ω inductive load directly to a gpio pin on an esp32 is all kinds of stupid.
No bass
What the name of he music if you give it to me i will make like
Audio Hertz - Mission to Mars

How much volt you give this board
USB 5v

@@afyu bro where do you from
Ukraine
How to remove that noise any idea?
use MAX98357 already with integrated amplifier

do esp31 have built in amp?
@@EnifOfficial not as powerful with my Arduino I can just connect two wires and make tone's play
Those speakers have no bass
Their tv speakers and in free air
RIP ESP32
Why
@@jesusv1nce929it's not built for that
1000% fake….
Where can i buy that speakers both wires
faked
It's not he just need to use a amplifier
It's not fake
You cant do that with aplifier lol
