I recently bought a few Arduino Uno clones. They were not cheap. They utilise the ch34 IC, which is a USB to UART solution. They all have SMD atmega328pb soldered on them.
The problem is that two of them stopped working with the Arduino ide. On inspection, i found out that my software was not updated so firstly I updated the software which now includes a configuration for the atmega328pb.
But somehow the internal bootloader in these SMD chips got corrupted and it stopped working. I then probed the chip with AVRdude prograamer.
Found that the chip is atmega328pb. The configurations were not included at the time of installation. But the avrdude program allows you added other avr parts from Atmel.
