Particle M-Hat with B524 M-Hat: Power-Optimized Edge Intelligence for Raspberry Pi Unlock advanced power management and connectivity for your Raspberry Pi projects with M-Hat, the next-generation hat designed to elevate edge computing, IoT, and machine learning applications. Whether you’re deploying AI models at the edge, transmitting remote telemetry, or managing battery-powered devices, M-Hat provides the tools to optimize energy efficiency and extend device uptime. Modular, Stackable, and Flexible M-Hat features three SMA connectors for external antennas, making it ideal for IoT applications with connectivity challenges. The stackable design, with an extended 40-pin female connector, provides built-in support for Raspberry Pi models 3, 4, and 5 and supports other Raspberry Pi accessories. Whether you need to add environmental sensors or connect peripherals, M-Hat offers the modularity to expand your projects easily. Seamless AI and Remote Monitoring M-Hat supports local model storage and over-the-air (OTA) updates, making it ideal for machine learning applications at the edge. The ultra-low power sleep modes keep your Raspberry Pi operational without draining energy, even in the most demanding setups. Built for IoT and Battery-Powered Devices With its integrated battery charger and power management system, M-Hat is perfect for remote sensors, cameras, and other battery-dependent IoT projects. Its ultra-low power mode ensures minimal energy use, with a dedicated wake pin for rapid activation when necessary. The PFET allows precise power control, reducing consumption by powering the Pi only when needed. The M-Hat supports various power sources (USB-C PD, DC, LiPo battery, and PoE HATs via the 40-pin header), giving you the flexibility to power your projects in diverse environments. Prototyping and Production Ready M-Hat is designed for both rapid prototyping and seamless transition to production. Engineers can benefit from its flexible I2C bridging, SMA connectors, and built-in support for Raspberry Pi models 3, 4, and 5. When you're ready to scale, M-Hat integrates smoothly with other hats and peripherals for full-stack IoT development.
