I know Arduino modules aren't generally compatible, but this looks like it could be. It's the Keyes KY-005 infrared transmitter.
There doesn't appear to be a data sheet anywhere online (and that's even a question on Stack Exchange).
Its outputs are signal, 5v, and ground. Here's the best info I could get on it:
Operating Voltage: 5V Forward Current: 30 ~ 60 mA Power Consumption: 90mW Operating Temperature: -25°C to 80°C [-13°F to 176°F]
Could I not plug the 5v into the Raspberry Pi's 5v output on the GPIO board, the signal to GPIO-17, and ground to ground?
This is how it looks:
My goal is to output a strong enough IR signal to turn on a TV from a normal distance (a meter or so is fine). I got a weak IR LED to work with LIRC, plugged directly into the Pi's GPIO, but of course this signal was too weak.
I want to avoid a breadboard with resistors and transistors, etc. This appears to be the standard Raspberry Pi solution, which I hope to avoid:
