Software package for the CH341A mini programmer, black edition, a 1.80 MB RAR likely holding drivers and flashing utility. The CH341A is a low-cost USB programmer widely used to read and write 24 and 25 series EEPROM and SPI flash chips holding BIOS and EC firmware. Technicians use it with a clip or adapter to back up and reflash chips. Note that some boards supply 5 V on the data lines, while many SPI chips are 1.8 V or 3.3 V, so check the chip voltage before connecting.
