درع الجرس Wemos D1 mini Buzzer Shield V1.0.0 ESP8266 أردوينو

The buzzer is loud enough to hear over my soldering iron fan, which is exactly what I needed for project alerts. Took maybe five minutes to plug into the D1 mini and map the D5 control pin in code.

Took me two minutes to solder the included pins and it clicked right onto the D1 mini. The four optional control pins are handy if you want to use something other than the default D5, and the 1-3kHz range handles my beeps and tones just fine.

Soldered it onto my D1 mini in about ten minutes and the 4 optional control pins made wiring a breeze, though the default D5 worked fine out of the box. Sound is a bit piercing at the higher end of the 1-3kHz range, but for alerts and beeps it does the job without any hassle.
