M5Stack Modules are stackable add-on boards that plug into the bottom port of M5Stack Core devices, expanding their connectivity and capability. Unlike Units which connect via Grove, Modules integrate directly with the Core's bus connector for tighter hardware integration.
The range includes communication modules such as LoRa, 4G LTE, GSM, and COMMU; power modules including battery bases and DC motor drivers; and sensor modules that add GPS or environmental sensing to an M5Stack Core stack.
M5Stack Modules are used in long-range IoT sensor networks, cellular-connected data loggers, GPS tracking devices, remote-controlled robotics, and professional prototype builds where communication range or power management beyond WiFi is required.
