After looking through the firmware very closely, I figured out a way to reduce power consumption of R48 via firmware tweaking. (Aggressive use of CPU “idle” mode while waiting for PWM pulse to output, etc.)
I managed to reduce the power consumption up to 43%. In my tests the batteries are lasting 50% or more longer!
All R48 will be shipped with the new, improved firmware as of today. If you already have R48, please send in for free upgrade.
