Nextion BOX Speaker

The sound quality is reasonable given its small size. I’m using it to provide a simple melody during system boot-up and for audible alerts during system faults. Overall, I'm pleased with my purchase.

i used this product for sound alert.
maybe better put in some short circuit protection in the RX and TX system. or fail or error in conection with microcontroleitor.
my suggestion is because three screens of the basic model have damaged the tx system when connecting it to microcontrollers,
for this reason the screen receives data but does not send it,
we have made the same connection with other nextion screens and the same controller and it works normally sending and receiving data. but only on these three screens of the basic model. They receive but do not send data despite having done multiple tests.
If you could provide us with a solution. (change a component of the screen).
I would be very grateful.

I just didn't expect that good sound from something so small.

Het is een mooi compact luidsprekertje dat een duideliijk signaal kan laten horen. Voor zo'n klein luidsprekertje is de geluidskwaliteit van muziek best wel goed. Ik gebruik hem vooral om een signaal te geven dus een wav. bestandtje met een enkele toon.

I used this speaker for an prototype display in our test vehicle. Sound quality is good. It would be very good, if itead provide a better technichal drawing, height of mountings is not given.
