DescriptionThe 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.Features PROTO Board for custom circuit prototyping with M5Stack main controllers Universal prototyping board with pre-soldered 2.54-15P straight male header pins M-BUS prototyping board support for bidirectional data communication and functional control 1mm hole diameter and 2.54mm hole pitch for common through-hole components 260-hole layout for flexible wiring, expansion, and development tasks Compact prototype board format for education, lab testing, and maker projects Specifications Board Type Universal prototype board Header Pre-soldered 2.54-15P straight male header pins Interface M-BUS interface Hole Diameter 1mm Hole Pitch 2.54mm Total Holes 260 Board Dimensions 50.0 x 50.0 x 7.0mm Board Weight 5.9g Package Size 138.0 x 93.0 x 8.0mm Gross Weight 8.1g Applications Rapid circuit prototyping with an M-BUS prototyping board Education and laboratory electronics exercises Small-scale customized project development M5Stack Core expansion and experimental hardware interfaces DIY sensor, connector, and signal-routing experiments on a prototype board Product List1 x Proto BoardOther ContentThe PROTO Board is intended for users who want open-ended circuit space rather than a fixed-function module. 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.ResourcesProduct documentationFAQWhat is the PROTO Board used for?The PROTO Board is used to build and test custom circuits that connect to M5Stack main controllers through the M-BUS interface.Does this prototyping board include header pins?Yes.
