Arduino OPTA

MicroPython version

I'm using Arduino Opta with MicroPython and two of them work fine. However, I ordered one online and encountered a problem after programming the firmware. Files in file explorers (Linux or Windows) are corrupted (special characters displayed and undefined files created). If I try to program it with Arduino, it seems to work fine.
I returned it to the reseller who sent me another one but it has the same problem.
Someone else have this problem ?
Thanks
Frédéric
