The utility model discloses a micro modulus hybrid fight recorder. The micro modulus hybrid fight recorder comprises a shell, a single-chip machine, a power supply interface and an FLASH chip, wherein the single-chip machine, the power supply interface and the FLASH chip are respectively arranged in the shell, the single-chip machine comprises a first IO (input and output) interface, multiple second IO (input and output) interfaces, an SPI (Serial Peripheral Interface) interface, an AD (analogue and digital) acquisition module and a crystal oscillator module. The micro modulus hybrid fight recorder is characterized in that serial ports are simulated by the IO interface of the single-chip machine instead of an additional serial port chip, thus the micro modulus hybrid fight recorder is low in power consumption and production cost, small in size and light in quality.
