I am using the cy8ckit-042-4200 board from cypress. The transistor is BC149C, base resistance is 330E, the motor is a tiny one used in RC helicopters, I thinks its called size 0.
Operating voltage of motor is 3.7 V, but for some mine works better at 5V.
I have managed a simple PWM, but I have abandoned the approach, as it is getting needlessly complicated. I am thinking of using wired control connected to pots instead of wireless.
The RC helicopter I have has a small chip, which is presumably the infrared receiver, and motor controller, but there is no name on the chip
thanks
