Review: Works great as long as you have the right expectations - These are good, cheap IR boards. As other reviewers have noted, the VCC lead on the transmitter isn't actually connected to anything; it's just part of the pin header. The transmitter is just an IR LED and a resistor; the DATA pin is really the + line, so if you send it current there, it turns on. You simply bit-bang on that pin to send pulses. If you're using something like a Raspberry Pi, you won't get great range, because all of the GPIO pins are 3.3 volts. I'm using it to control an A/V receiver and have the LED right next to the panel, so it works great. If you need more range, though, you'll want to hook it up to the 5v rail via a transistor and probably also surround it with an IR reflector (as-packaged, it's an omnidirectional LED). The IR receiver works just like you'd expect, and obviously it _does_ need power, so all three pins are needed: data, vcc (5 volt, although might work with 3.3; I didn't test that), and ground. I believe data is pulled high and drops to ground when a signal is received. If you're using a Raspberry Pi with a reasonably current OS, you don't need to download any drivers; much of what you see online is old. Add the appropriate lines ("dtoverlay=gpio-ir,gpio_pin=" and "dtoverlay=gpio-ir-tx,gpio_pin=") to /boot/config.txt (or /boot/firmware/config.txt if running Debian 12). Note that, if you are going to both send AND receive (i.e. you have both lines in the config file and you've hooked up both boards), you'll need to specify which device to use (--device=) in the ir-ctl command: one will be /dev/lirc0 and the other will be /dev/lirc1; this is why some of the reviewers couldn't do both at the same time. Simply use the 'ir-ctl' command to send and receive pulses. ir-ctl can read to and write from a file, so to train it, just set it to write to a file, and then you can play those exact commands back by reading from the same.
Review: Updated Review: They Work Flawlessly - NEW REVIEW, 4/27/21: I'd like to apologize to Dorhea; my initial problem stemmed not from faulty units, but rather misinformation from everywhere else. The reason my units weren't transmitting was because I'd been connecting the signal wire, per literally everyone's instructions, to the wrong pin on my microcontrollers. Once I discovered the proper pin, I retried these transmitters, and they finally not only worked, but performed better than I'd thought they would, with more range than I'd expected. I now fully endorse these products, I fully recommend them, and I hope I haven't turned away too much business. FIRST REVIEW: When you apply these to rebuilds of examples from the handful of tutorials available for this module, no matter how faithfully I've followed said tutorials, these modules just don't work. It's like they can't even power up. What's worse is "DORHEA" is inaccessible for support. I should've known given the lack of reviews or questions. If you're reading this, try a different company, for instance, the equivalent models from Gikfun. In fact, I just bought their IR transmitters. You'll probably have better luck with them.

## Features

- The infrared transmitter module is directly transmitted by a single tube, and the waveform needs to be modulated by the program.
