I am working on a project that I plan on running off a 3.7v li-po battery.
I will be running 4 high powered leds in parallel and an Adafruit Pro Trinket (5v version) so obviously I need to step-up the voltage. But for the Pro Trinket, I'm assuming it needs around 7 volts like the arduino for the power regulator to work properly. However, the LED drivers I wanted to use here:
can take a max of 5.5v. I'm also worried about supplying to much voltage to my LEDs.
So, here are my questions:
Do the led drivers protect against over voltage?
Where can I find different LED driers that can be controlled via pwm that can take higher voltage? I tried to find them but these supply websites are impossible for a newbie like me to navigate.
Should I use the 3v pro trinket? Would it power my sensors, N-channel mosfets, etc okay?
How can I power the Pro Trinket?
Would a 7.4v battery be better?
Thanks in advance.
