Buzzer device on the CLUE

by defragster on Fri Jun 26, 2020 3:35 pm

What is the part used for the CLUE buzzer?

The other onboard devices are called out but that buzzer looks nice and sounds okay, and would like to see about adding it to the SENSE units I got.

Maybe it is called out on the Eagle drawings? Will need to know if it power direct form a pin or if it takes helper parts to power it.

The CLUE speaker does have a surprising amount of oomph for such a small device. There's a previous discussion here on the fractionally larger speaker used on another board: What is the speaker on the Circuit Playground Express?.

Thanks, will look into that - it seems to be built with an amp based on follow-up. Looking for simple equivalent - CLUE might offer all that is needed for a single tone and maybe some feedback sounds.

The Clue Learn page shows the Schematic and notes a 5mm BUZZER and the circuit to power it:
https://cdn-learn.adafruit.com/assets/assets/000/087/877/original/adafruit_products__CLUE_sch.png?1580423083

But it does not give the part number to order? Can that be published?

The prior link for the CPExpress is : https://www.digikey.com/product-detail/en/cui-devices/CMT-7525S-SMT-TR/102-3745-1-ND/6012446
> maybe the same CLUE circuitry could drive that larger 7.5mm buzzer?
