Hi,
I have only very little knowledge about audio circuit (amplifier, filter, etc), so please forgive me.
What should be the recommended circuit to connect to the audio output pin (AUDIO_L) on BT815/6 ? So that it can working to play a sound/tone/voice.
and also at the end of the circuit should be connected to a speaker right?
What is the specification of speaker for use with EVE BT815/6 chip?
Thank you.
Hi,
We have an example circuit in this development module below (see page 11)

This circuit can be used with the CleO Speaker below, you can find the spec of the speaker used in this datasheet

I see, so it will work with 0.5W 8Ohm type of speaker, I will try with SMD speaker soldered onboard.
Thank you
It is possible to connect the audio output line to the auxiliary of any speaker, just share GND between the MCU and the speaker. You can even use a bluethoth audio transmitter
