433mhz RF transmitter

Projects General Guidance

Hello guys,
I've searched a bit for tutorials on how to use KL-200 433mhz RF transmitter, however i did not find any. I'm scraping some parts to use with arduino/ESP32 and instead of buying a RF transmitter i scrapped this transmitter from an alarm buzzer.
Can you guys take a look at the transmitter and tell me how i should connect it, or guide me through it, and if you could also explain the proccess that would be amazing.

Best regards,
Vasco.

This appears to be a PT2262 compatible transmitter module intended for pushbutton remote controls.

The jumpers on the module need to be set to determine the data and address to be transmitted. You just power it up to send the 12 bit "message" set by the jumpers.

See the above linked data sheet for some guidance.
