Description The PROTO Board is a universal prototyping board for building custom circuits around M5Stack main controllers. This M-BUS prototyping board comes with pre-soldered 2.54-15P straight male header pins, so it can connect through the M-BUS interface and support bidirectional data communication and functional control during circuit development. This prototype board gives makers, educators, and hardware developers a compact area for wiring components, testing ideas, and creating small custom extensions. The 2.54mm hole pitch matches common through-hole parts, while the 260-hole layout gives the PROTO Board enough flexibility for rapid experiments and iterative hardware validation. Use the M-BUS prototyping board when a project needs a simple way to add sensors, connectors, pull-up parts, signal routing, or small interface circuits to an M5Stack Core system. The PROTO Board is especially useful for rapid circuit prototyping, education, laboratory work, and small-scale customized project development.

Its 2.54mm pitch helps simplify soldering and component placement, and the pre-soldered header reduces the setup work needed before starting a prototyping board build. When using the M-BUS prototyping board, confirm component orientation, signal level, and available space before soldering. The PROTO Board is best suited to compact add-on circuits, quick tests, classroom demonstrations, and early-stage functional verification.
