I just find some PWM board which will provide 5 different mode for any single mode driver. For example, it can turn flexdrive, microboost drive, or other drivers 1 mode drivers into five mode, which includes low-mid-hi-strobe-s.o.s
The PWM board will hold up to 1A and it is 17mm so it fits most of the host from AA to 26650.

REMINDER: This is not a driver board. It only provide 5 modes signal to 1 mode driver board.

The price will be around $6 with $1 tolerance. It will be around 5-7 dollars depend on the discount from the manufacture.
 
Well, anyone ever measure the turn on characteristics on a scope of the flex drive? Does it have a soft start? If it doesn't, your not going to want to PWM it.

In addition, PWMing a switching power supply could be rather dangerous at high freq. Could cause the output to become every unstable. Finally, both the flex drive and any drive has capacitive loading so theres going to be a limit as to how fast you will be able to PWM it before it stays always on.

However, if all you want to do is low freq such as between 0-30hz (human eye range) then its feasible :) Any chance you know what frequencies the modes are at?

Hi! Random Person can you tell us more? Because I don't want to sell a thing that kills a bunch of expensive drivers.
