I have been using this device CH341 for readinng and programming mainly BIOS for PC. I m trying now to read a 5P08C3 eeprom from my ECU to get the file and write it into a donor ECU eeprom. It seems the reading is ok (however I get sometimes different readings). My understanding is that it is possiblr to mod the CH341. M;y intent is to put a switch so that I can give 3,3 or 5 volts. I guess the 5 volt MUST be supplied to the Vcc pin (pin 8) of the chip. Is this correct?
