I’ve bought two RFM69HW modules from a chinese dealer. (Please no comment about that )
After trying a couple of hours to get these to communicate with each other I noticed that the modules only was labeled as RFM69 and 433MHz. So I don’t know if it’s just some sloppy labeling or if I got the wrong type of modules. In this thread I’m only interested in if anyone can help me to identify the exact type of module. (no question about the source code)
The chip says: H RF69 1547 W3F723
The crystal(?) says: 32.000 MHz-H
Adding two pictures of one of the modules.
(The big black thing in the upper left corner of the “front” picture is just a single pin female connector I’ve soldered to be able to easily test different type of wire antennas.)
