XGecu is a line of programmers from Haikou Xingong Electronics Co.,Ltd. Their devices include:

  • TL866 universal programmer (widely cloned, replaced by the TL866 II PLUS)
  • TL866 II PLUS universal programmer
  • T48 universal programmer
  • T56 universal programmer
  • Various CAN bus equipment (out of scope for this wiki)


  • Haikou Xingong Electronics Co.,Ltd: official company name
  • XGecu: line of programmers made by Haikou Xingong including TL866, TL866II, T48, and T56
    • Also known as autoelectric, but this name seems to have fallen out of use
  • minipro: software to control TL866 hardware
    • Notably the proprietary Windows software, but the Linux FOSS CLI software is also called "minipro"
    • Confusingly the original TL866 also says "minipro" on it


They have a table on their website: http://www.xgecu.com/
