Product Description
The NULA DeepSleep ESP32-S3 is a powerful development board engineered for ultra-low-power IoT applications. Built around the ESP32-S3-WROOM-1-N8R8 module, it combines a dual-core processor with 8MB of Flash and 8MB of PSRAM, providing ample resources for complex projects. The board’s standout feature is its exceptionally low deep sleep current of just 7µA, making it an ideal choice for battery-powered devices where power efficiency is crucial. With integrated Wi-Fi and Bluetooth LE connectivity, the NULA DeepSleep is the perfect center-stage for your embedded projects! Due to it’s ample connectivity, it excels in general use applications as well, such as display driving and wireless communicating.
It features an integrated PCF85063A real-time clock (RTC) for precise timekeeping, even when the main processor is in deep sleep. Power management is handled by an onboard TP4056M Li-Ion/Li-Po battery charger, allowing for battery integration and charging. The board’s design ensures stable performance and provides all the necessary components for a long-lasting IoT solution right out of the box.
Power your next project with the NULA DeepSleep ESP32-S3 if you are building remote environmental sensors, asset trackers, or low-power wireless nodes. This board provides the performance and efficiency you need with its breadboard-friendly layout that makes prototyping quick and easy, while the rich feature set supports a wide range of applications.
