  • Ok, that works!

  • What is the maximum voltage that the regulator can handle? Is a 12 volt supply too much?

  • The motor will most likely spin in reverse if you apply the voltage in reverse.

  • I would enjoy a breakout board for interfacing with jumper cables. A standardized 8 pin breakout board is what we are looking for.

  • I want to use this chip with the ESP 8266 Dev Board which lacks a sufficient 0-5v ADC. Is there a library for use with this chip? I have never used an SPI device without a library…How does one go about doing this?

  • Tenthed

  • Thanks for the response. I do have the tools to build this into an off the shelf project enclosure. I plan to pick one of these kits up as soon as the new ESP32 is in stock! Please do pitch the idea…it would be better than a sloppy DIY solution.

  • I am not sure but I think it would be easier to use a normal piezo buzzer and control the tones directly from the Arduino. You could use the tone(pin, frequency, duration) function to do so.


  • I would get this if it it came with a better enclosure, as in a plastic case that would be sold separately.

  • What is the easiest way to solder wires onto these? I have the Hakko soldering station sold by SparkFun and stranded 22awg wire. When I try, the wires either tough the other terminals or the solder bridges the gap. Is there any chance that SparkFun could offer a breakout board with headers?
