Hi!
How can I configure the passive buzzer on the Seeed Studio Expansion Board Base for XIAO in Mestashtic?
Does anyone have a tutorial on this?
With New Year’s greetings,

Hi there,

and Welcome here, Head over to the WiKi for the Expansion Board… There is a demo for how to play Happy Birthday , LOL… on it!
It’s on A3 on the Xiao , and there are some drag and drop Uf2 files in a thread called “drag and Drop Testing” to address all the peripherals on it. :+1:

HTH

As pj say buzzer is on a3… you probably need to check the hardware page to see what physical PIN number that is… as for
Meshtastic… theoretically you can set the pin in the app somewhere but you gotta play with it… I hope if you find a tutorial you can share that t here

I found in the documentation that the A3 output is on GPIO4 and that’s how I set it on the Meshtastic Web page (Config / Module Config / External Notification Settings):
Module Enabled = ON
Output Buzzer = 4
Alert Message Buzzer = ON
Alert Bell Buzzer = ON
Its works!
