Product overview
Description
This board has been physically tested and validated; it is not for sale.
The STEVAL-RFPLUG01 evaluation board is designed to be used in home automation for Internet of Things (IoT) applications and embeds the core functionality required for a secure communication.
The board is designed with the STM32L443CCT6 microcontroller based on the ARM® Cortex®-M4; it runs at 48 MHz. Power consumption is between 40 and 50 mA.
The STEVAL-RFPLUG01 has two modes: in the first mode, the device acts as a BLE peripheral to control and monitor the system; in the second mode, the device is a manufacturer-specific beacon advertising its metering parameters so that multiple Android devices can monitor the plug.
The on-board SP1ML-868 controls the system remotely with 868 MHz connectivity, and the non-isolated buck converter supply is designed using VIPER06XS (ideal for applications where large current is not needed and small form factor is required).
A Triac controls the current and acts as an AC switch for various electrical system applications.
You can use an Android application by STMicroelectronics to turn load, scheduling and dimming features on or off, and check the metering parameters.
