Power Management
STICKER is designed for ultra-low power operation to enable long lifetime in the field without external power sources.
It is powered by two standard AA batteries, which provide a compact and widely available energy source.
Energy Harvesting via NFC
- Thanks to its NFC interface, STICKER can be configured even when batteries are not inserted or depleted.
- The NFC field from a smartphone provides enough energy (energy harvesting) to write configuration data into the internal EEPROM of the NFC tag.
- When the device wakes up on battery power, it validates the configuration, applies it, and clears the temporary storage.
Optimized Consumption
The STM32WL System-on-Chip enables ultra-low power operation, making STICKER suitable for long-term battery-powered deployments.
Combined with efficient onboard power management, the device is designed to achieve very long lifetime in the field.
