Frequently asked questions
How do I wire the UM66T-19L?
Pin assignments, supply voltage and speaker connection are defined in the UM66T-19L datasheet. Check it before wiring, as the chip is not a standard development board module.
Can it drive a speaker directly?
This depends on the output stage described in the datasheet. Some melody ICs of this type need a transistor or amplifier stage for a louder speaker, so confirm this in the datasheet before connecting.
