CH341A based Programmers are cheap USB Dongles usually used for reprogramming SPI chips. SPI EEPROM chips are found in most many electronic devices. [1]
CH341A Programmers usually only output 5V. If used with chips that require 3.3V on the data lines, it could irreversibly break them. Some BIOS chips, for example, require 3.3V. For a safer alternative, see the Raspberry Pi Pico. [2]
