What I'm writing here is not specific to this motor (since I couldn't find the specs on the page you sent), but general to most hobby R/C equipment. Hobby servos and speed controllers almost always have the same kind of control signal. It is a PWM signal at 50[Hz] with the pulse width varying between 1[ms] and 2[ms]. 1[ms] represents one extreme (position in the servo case, speed in the ESC case) and 2[ms] represents the other. For an ESC, 1[ms] may mean "stopped" or it may mean "full speed in reverse". The control signal is nominally 5V, but most equipment would work just fine with 3.3V.
PPM signals are yet another form of signals commonly found in hobby R/C equipment, but those are used for a different purpose: to multiplex multiple channels on a single signal. Normally, this would be the signal that gets modulated over the radio. It is generated by the remote, then decoded on the vehicle side into multiple servo/ESC signals as described above. I hope this makes sense. I had the same problem to get started as you do a few years ago.
