32-
bit MCUs are much faster and generally have better capabilities (floating-point, on-
board DSP) than 8/16-
bit MCUs. Note: some
boards, particularly if designed as Arduino "Shields", may actually also be compatible with an 8/16-
bit MCU. For more information on
32-
bit boards see List of
32-
bit electronics.
