I’m assembling & testing some of my products, and have discovered that 3 out of the five 3.5" Enhanced Nextions are faulty.
These were purchased from Bangggood in early June.
The display displays things, so you’d never know by a casual look, but the EEPROM appear to have faulty memory locations.
ie; some of the data is not coming back after power cycling, as it should be.
A visual inspection does not reveal anything obvious nor different to the other 3.5" displays on hand.
No solder defects around the 24C08N or incorrect parts.
(Sometimes an SMT pick & place operator might load the wrong reel)
I have bought 26 of these displays over the last few months, and these are the first faulty ones I have encountered.
Anyone else received some bad “Enhanced” displays recently?
