Description The M5Stack BUS Module is a stackable M-BUS prototype expansion board for M5Core projects that need custom circuits inside the M5Stack module system. It provides a universal prototype board with 200 board holes, allowing the module to interact with the host through M5-Bus while keeping the stackable module format. Official usage note: When using the pin breakout, cut the grating on the side of the Module Bus so external pin connections are easier to route. Features M-BUS prototype expansion board for custom circuit design and signal breakout. Stackable module that connects to M5Core and other modules through M5-Bus. Universal prototype board with 200 board holes and 2.54mm IC pitch. Supports extending the M5-Bus to the other side of the module for pin breakout. Includes a 2*15P 90-degree pin header for external connection work.
