In regard to that last item, that motor is, as the subject states, a Tamiya Atomic-Tuned (whatever that means ) motor. Most of the info is in Japanese, although there are a few Arabic numerals — you know, digits 1 through 10 that we're familiar with.
At the top of the back of the package is some Japanese characters, followed by 2.4V (which I think is the input voltage — a few lines down, is some Japanese, then (V) 2.4~3.0, which I'm guessing is the acceptable range of power for the motor).
Back to the first line: (mA) 1,300
Next line is (rpm) 13,700... (rpm) 15,700, and skipping to the last line, the weight and dimensions of the motor.
I expect to use the motor only a few minutes a day, at least initially. Maybe later I'll design and build a robot of some kind, a project that'll keep the motor running more than a few minutes a day. And of course control it via WiFi.
Question: the ESP outputs 3.3V, whereas the motor expects a maximum of 3V. Would feeding the motor 3.3V harm either or both the ESP or the motor? If so, what kind of resistors would I need?
For whatever it may be worth, attached is a scan of the back of the package.
Thanks in advance for any help
