  • The EV3 intelligent brick is powered by 6 AA type batteries. The NXT Education version comes with a rechargeable lithium battery pack with an AC plug. This power source can be used with the retail version of the EV3 without any problem. The rechargeable battery pack simply replaces the bottom cover of the NXT Brick, although it does increase the overall height of the NXT by one stud so one must be careful and leave sufficient room when building with the standard NXT if a rechargeable battery will be used in the future.


  • .EV3, the official LEGO EV3 visual programming environment
  • RobotC by Carnegie Mellon University, including the [ Robotics Academy: a C-based programming environment designed to work on the RCX and NXT was developing support for the EV3 as of February 2014.
  • BricxCC (Bricx Command Center) by John Hansen: an IDE for programming the the various LEGO programmable bricks will support EVC, leJOS, and the GNU C/C++/Pascal compiler for the ARM9 linux.[JH] Test releases of BricxCC can downloaded here.
  • C/C++ using the Sorcery G++ Lite toolchains[LM3] and other languages as they mature.
  • python
