Board

Picture: korobo_2-1_bno055_ver3-2_img1.jpg

Overview / Overview

The printed circuit board of Korobo (2nd generation) focuses on ease of assembly and maintainability.

  • Compatibility with universal boards (2.54mm)

    The pitch of all through-holes provided on the printed circuit board is 2.54mm. In other words, it is compatible with commercially available universal boards, so even those who have difficulty procuring printed circuit boards can build it (in theory...).

  • Connection via pin sockets and pin headers

    The main board and various modules are connected by pin sockets and pin headers. Therefore, they can be easily removed, which allows flexible handling of failures and replacement of the microcontroller board.
