What this episode covers

David Su, co-founder and CEO of Atmosic Technologies, discusses his career journey from HP Labs and Atheros to founding Atmosic, where he leverages decades of RF design experience to create ultra-low-power wireless chips. He explains how Atmosic’s configurable SoCs support Bluetooth, Zigbee, and Matter over Thread, achieving power levels 3-5 times lower than competitors by optimizing circuit, system, and software interactions. Su highlights the critical role of energy harvesting, particularly photovoltaics, in enabling battery-free IoT devices, and reflects on the balance between structured engineering and innovative craftsmanship learned during his time at Qualcomm and Atheros.

    Reducing Battery Waste with Low-Power IoT | Atmosic's Nick Dutton | Internet of Things Podcast

    Nick Dutton, Senior Director for Product Marketing at Atmosic Technologies, explains how focusing on ultra-low power consumption enables energy harvesting, thereby reducing the massive environmental impact of battery waste in IoT. He details how Atmosic's ATM33 Bluetooth SoC integrates energy harvesting capabilities to eliminate or extend battery life in applications like TV remotes and electronic shelf labels. Dutton argues that sustainability is driven by both environmental mandates from tier-one customers and the logistical/financial burden of maintaining large-scale commercial deployments.

    An Interview with Felix Rusu

    Felix Rusu of Low Power Lab explains how he built a home automation ecosystem using sub-gigahertz radios and low-power microcontrollers to avoid the range and power limitations of 2.4 GHz Wi-Fi. He details the design of the Motino board, which uses an ATmega328P and custom libraries to manage RFM69 modules, enabling features like automatic transmit power control and wireless firmware updates via external flash. Rusu discusses the trade-offs between RFM69 and LoRa, emphasizing that for most residential applications, RFM69 offers sufficient range with lower complexity and cost, while highlighting the importance of keeping data local on a Raspberry Pi gateway rather than relying on the cloud.
