Overview

In an era where battery life is measured in years, security must withstand physical attacks, and intelligence must live at the edge not in the cloud the nRF54 Series from Nordic Semiconductor represents one of the most significant leaps in low-power wireless silicon since the original nRF52. This comprehensive, hands-on guide is the definitive resource for embedded engineers, IoT product designers, firmware specialists, and hardware innovators who want to build tomorrow's connected devices today. What You'll Master The complete nRF54 family architecture: from the ultra-low-power nRF54L15 flagship to the Axon-NPU-equipped nRF54LM20B and the high-performance nRF54H20 Fourth-generation 2.4 GHz radio: record-low RX/TX currents ( 3.3 mA / 4.9 mA), native Bluetooth 6.0 Channel Sounding for cm-level ranging, Thread/Zigbee/Matter, and Wi-Fi companion integration Multi-core design: Arm Cortex-M33 + RISC-V SoftPeripherals coprocessor for flexible, future-proof I/O Edge AI acceleration with the Axon NPU: deploy TensorFlow Lite Micro models for anomaly detection, keyword spotting, gesture recognition, and predictive maintenance all while consuming 50-300 μW during inference PSA Level 3-aligned security: TrustZone-M isolation, tamper mesh, side-channel-hardened crypto, secure boot, and lifecycle management Ultra-low-power design patterns: achieve 3-15 μA average currents in real products (beacons, wearables, industrial trackers, smart-home sensors) → multi-year coin-cell lifetimes Full migration path from nRF52 / nRF53 codebases to nRF Connect SDK + Zephyr RTOS Four production-grade projects: Battery-powered BLE beacon with Channel Sounding Matter sleepy end device over Thread Low-voltage wearable health monitor (nRF54LV10A focus) Industrial asset tracker with on-device AI anomaly detection Who This Book Is For Embedded C developers moving from nRF52/nRF53 or STM32/ESP32 who want dramatically longer battery life and modern features IoT product teams designing next-gen wearables, asset trackers, smart-home sensors, industrial monitors, healthcare devices, or edge-AI endpoints Engineers in emerging markets seeking cost-effective, power-efficient, globally certifiable wireless platforms Students and researchers exploring Bluetooth 6.0, Matter, tinyML, or ultra-low-power multiprotocol systems
