MINICUBE2 is a multi-function emulator (on-chip debugging + flash programming) which is small (48x48 mm2), light-weight, low priced. This single unit covers it all from debugging to mass production. This product supports serial connection, JTAG connection is not supported. For details refer to the documents of the MCU you use.


  • Small and light-weight
    Since it's 48mm×48mm×13.9mm, small and light-weight, it can save space in development/mass production, and it's also easy to carry.
  • Low price
    Compared to the MINICUBE, MINICUBE2 costs one-third the price, which can reduce your initial costs for development and mass production.
  • Mode LED
    The appearance of the mode LED changes according to the status of hardware and software.
  • Self-testing function
    MINICUBE2 has a self-testing function, which is used to detect faults in MINICUBE2 and perform maintenance.
