Walter, a cutting-edge certified ESP32-S3 module with LTE-M, NB-IoT, and GNSS capabilities, set to revolutionize IoT(Internet of Things) prototyping and production. This compact system-on-module combines the robust ESP32-S3 processor with a powerful 5G modem and GNSS receiver, providing a versatile solution for a myriad of applications. Walter is not just for prototyping; it's certified for FCC, CE, Australia SDoC, and New Zealand SDoC, ensuring reliability in both development and production. With a remarkable ten-year availability guarantee, Walter stands out as a dependable building block for long-term IoT projects.
Walter simplifies the development process with 100% open source software libraries, supporting popular languages and toolchains like ESP-IDF, Arduino, Micropython, and Toit. Programming is a breeze – no special dongles required; just connect Walter to your development machine via a standard USB Type-C cable. The module comes with built-in Wi-Fi and Bluetooth antennas, while LTE-M/NB-IoT and GNSS functionalities are optimized using external antennas with u.FL connectors, in collaboration with recommended partner Taoglas.
Designed for seamless integration, Walter can operate standalone or be plugged into the specifically crafted carrier board, Walter Feels. This carrier board facilitates rapid development, boasting features such as a wide input range, MPPT (Maximum power point tracking )power input, battery charger, SD card slot, multiple sensors, and various interfaces. Whether used for a GNSS tracker, remote weather station, tank level sensor, or countless
other applications, Walter's versatility knows no bounds. The project's commitment to open source values is evident, with comprehensive documentation, open schematics, and active encouragement for community contributions.
As Walter gears up for production, the team has meticulously refined its design for manufacturing. The module's industrial-grade specifications, pending certifications for CE, FCC, Australia, and New Zealand, and European Union-based production.
