What is the setup process?
The S2 module comes pre-configured with a data plan and is ready to use out of the box. Simply enter the IMEI into the Superstack platform and press the connect button on the S2 hardware to complete the setup.
How do I program the S2?
The S2 module features our real-time Lua scripting engine that can be programmed and debugged remotely through the Superstack code editor. You can update code and fix bugs from the cloud, even after your S2 is deployed in the field.
What types of sensors can I connect?
The S2 module provides four simultaneous serial interfaces, including two high-speed SPI interfaces suitable for cameras and displays. Pins can be configured for various functions including GPIO, I2C, PWM, and analog input, enabling connection to a wide range of sensors, actuators, and other peripherals.
How is the device powered?
The S2 can be powered via USB-C, an external 5V power supply, or an optional 4.2V lithium battery. It features an advanced power management IC for battery charging and provides two adjustable voltage rails for powering external peripherals.
How much data can I transmit?
The S2 module uses LTE Cat-M1 with speeds up to 1Mbps. Typical messages include sensor readings formatted as JSON strings, where the message size in bytes corresponds to the total character count. Data transmission is limited only by your Superstack usage tier, which determines the overall data allowance across all your devices.
What security features are included?
The S2 module establishes secure cellular connections to the Superstack cloud platform via LTE-M, with data encrypted using DTLS 1.2. All data is stored in a secure cloud database and is accessible only through authorized Superstack accounts or via API keys.
What AI capabilities are available?
The Superstack platform's AI can analyze your aggregated data through natural language queries. For example, you can ask "What is the average temperature across all field sensors right now?" or "How many trucks entered the factory in the last hour?" The AI interprets these questions based on available data, sensor types, log messages, and data labels. These queries are also accessible via the Superstack API for integration with your own applications.
When will the S2 be available?
The S2 module will be available through Digi-Key in summer 2025. Sign up for our mailing list above to receive availability notifications.
Where is my data stored?
All data is securely stored in the Superstack cloud database. Enterprise users have the option to forward all data to their private cloud infrastructure using REST hooks.
Can I create dashboards in Superstack?
While Superstack focuses on device fleet management, programming, and AI analysis rather than dashboard creation, you can easily integrate your data into custom dashboard applications using our API for real-time metrics.
