MADI Development Board
Boards produced by libmcu are divided into core boards and extension boards.
Several types of core boards are manufactured in the same form factor, 30x21.59mm long. Because data communication and debugger connection are possible through the Type-C USB port of the core board, the core board by itself can fully play the role of a development board.
Extention board is a board to which various sensors and functions are added. A suitable core board can be attached/detached to the extension board.
Schematics for boards can be found here.
