Sushi IoT Framework

Sushi IoT is a firmware framework for ESP32-based boards that combines solid system management with the flexibility of MicroPython

It is useful for students and makers to accelerate projects by using reliable building blocks to manage core functions, allowing you to focus on application development without getting lost in low-level system details.

New here? Take a look at a few real project examples to see Sushi IoT in action.

Main resources

Applications

  • Student experiments
  • Home automation systems
  • IoT hubs
  • Alarm systems
  • Domotics servers
  • Remote monitoring and data logging systems (e.g., weather stations)
  • Local and remote control systems (via local interface, web interface, or modem)

Overview

Overview

Features

Works on very common commercial boards based on ESP32 SoC, widely available online for DIY electronics projects.

It simplifies development:

  • Hardware management: Wi-Fi, LCD, keyboard, modem, I/O expansion, relays, power detection, battery level, buzzer.
  • Software features: System management via web UI (network and system settings, logs, status, etc.) and a physical interface for on-device menus.
  • Embedded MicroPython environment: Users can run their own scripts freely, while built-in libraries provide optional system management features.
  • Embedded high-level MicroPython libraries for rapid access to hardware and software functions (custom menus, web pages, I/O expansion, SMS, HTTP requests, etc.).

Manages all essential components typically present in an IoT system, regardless of the specific application:

  • Physical interface management (keyboard, display, status LEDs)
  • Wireless connection as client or access point
  • Drivers for all hardware components present on the board (I/O expander, modem, etc.)
  • Web interface with user-level access (web server and UI)
  • Modular menu management for physical interface
  • High-level API for many typical functions: HTTP requests, SMS, GSM calls, web server extension, I2C communication, etc.
