First thing to decide is your range and IR immunity. If your range is short,
and no other IR devices are in sight, a transistor driver + IR led at the TX
end, and an IR photodiode at the other end would do. Else, you'll have to
use those IR modules.

Protocol wise, USART direct from the PIC should not be a problem.

Subject: [PIC]: How to implement a Infrared communications
