Yes it is.All chips do that, including real or fake MAX chips and also any chip I have come across in the last 40 years.
The fake MAX7219 chips take power from signal lines in a destructive way.
They are unreasonably intolerant of signal voltage higher than VCC.
Have you had any success using the fake MAX7219 chips in a long line?
The design length is 18 modules (6 feet).
However, as the Vcc line grows in length, and the load from the modules increases, the Vcc can find itself lower than the signal lines. When this happens, one module at the end can corrupt the entire chain by inserting random spikes on the signal lines.
I found no evidence that the real MAX chips exhibit the same dysfunction. 0.3V over might be normal for normal chips, but I believe it is much less for these fakes.
You seem to have successfully hijacked this thread.
You haven't really explained what modules you are using.
If you have any concerns about power loss when chaining them, then it is patently obvious that you have failed to correctly supply the power. Rather than complaining about it, you need for a start, to run a supply cable of adequate gauge not only to the start of the chain, but also in parallel to the end and possibly to the middle as well.
Have you used the software SPI as Marco explains in reply #11?
