same pin out (yes, even the DB15 connector)
Q24PL001 module
Fully certified
No Migration, no validation!
Not quite - see: viewtopic.php?f=30&t=3026
The M1306B was a Q2406
Not necessarily true; eg, see: viewtopic.php?f=30&t=3026
Not true - you do need to check that none of these subtle differences affects your particular application!
I’m not knocking the product - but it isn’t true to say that it’s a 100% drop-in replacement.
