I apologize ahead of time if we are only supposed to talk about Arduinos. But, the Teensy is super small and has more ram than the mega.
My issue is that I want to control LED strips using the teensy, but it seems the logic level outputs are only 3.3v which wont work, so I need a buffer to increase the voltage.
What do you recommend. Ideally, id like something easy to solder (through pin)
Also, I need 5v for the teensy and a 433mhz receiver from a 12v supply (the leds run on 12v) so could I use a voltage divider here? Thanks!
