Aaah - That’s why. I’m using that YAML, and that is based on using an external speaker?
Or is it the same YAML for internal speaker?
It’s not much related to YAML, because the DAC (PCM5100a) carried by the hardware does not have enough power to drive large speakers, so the sound will be very low. You need a speaker with battery power or external power supply to get louder volume.
Just like this, 3.5mm to BLE.
Yes, I know that. But there should be an internal speaker on the device, but I cannot get any sound from it.
There is a DAC inside the device, but no speaker. Are you sure it’s the same device?
If it is the same device, in any case, you need to insert the speaker into the 3.5mm jack to hear the sound
OK. So there is no speaker, but there is a mic.
Thanks. Then I have to rethink a bit here.
How is the mic doing for voice assistant duties? Both from up close as well as some distance away would be interesting. I would love a voice assistant with a screen on my night stand…
It is not as good as Voice PE because it only has one microphone. It works well for wake-up and commands in environments with less noise. I find it quite satisfactory to use it in the bedroom.

Probably worth a shot then, trying to decide between this, a bigger esp32 screen and a full out tablet solution just now… Thanks for the feedback!
Great news with ESPHome 2025.5!
The required Quad SPI component is now available, and compatibility with the JC3636W518 display is officially listed 
Has anyone already got a working YAML or even a full step-by-step guide for getting it up and running?
Also, do you have any tips on the best way to flash it with ESPHome? Should I use USB or go directly via RX/TX on the board? If the latter – what’s the best way to open the device without damaging it, and how should it be wired?
