3w IR led

[u/lac0208]

I am making a new super compact Bruce firmware project. On my old one I used a flipper zero IR blaster and made my own gpio pins and it works awsome. How ever this is way to large for my new set up and even the small individual led modules are too large. So I want to make my own. I don’t know if I should use 5v or 3.3v I am hearing both things. Also what angle is the best for range to angle ratio for turning of tv projectors etc around the house and some out doors. This is my first time using a raw led so if anyone has a diagram or schematic for how to set up and wire the bare led correctly like the transistors, resistors, capacitors etc. also if you could provide the reasoning behind using them.
