Type Dongle

CH341A based Programmers are cheap USB Dongles usually used for reprogramming SPI chips. SPI EEPROM chips are found in most many electronic devices. [1]

Risks

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]
