It's one of these (though maybe not from this specific listing): https://www.aliexpress.com/i/3256801296478138.html?gatewayAdapt=4itemAdapt. I've measured a few and they are around the 17 ohm mark with no click (that I can hear).   Volhout said   You cannot drive it from a picomite pin directly. I assume you mean it is inadvisable, since using the PWM command I was able to do exactly that. Note both Mick and Peter have mentioned 5V, these are listed as 3V/3.3V ???
