Information on how to make sounds from the Presense

Asked 3 months ago, Updated 3 months ago, 9 views

For more information on connecting speakers to the Presense and making sounds

I'd like to connect the speakers to JP8 and JP9 on the Spresense expansion board and play the sound.

We are considering implementing it in an arduino-SDK environment, but from JP8 and JP9 on the expansion board
How do I play sound from the speakers?

It's not an official method, but you can use R15, R16, R17, R18 to shorten it easily. Some of you have already done it, so you might want to refer to it.

Here's how to use the speakers.
It seems that the main board needs to be renovated.

(Here's an excerpt from the manual)

The main board is set to match the headphone output of the expansion board at the time of shipment.To use the speakers, you need to replace the chip parts on the main board and solder them to the expansion board. This will involve soldering of small parts and remodeling of substrates, so please be careful only if you have the right skills and equipment.
