IoT Training Board Without Circuit Assembly

# Universal IoT Training Board: Hardware Foundation Without Circuit Assembly

Students and schoolchildren can jump straight into programming IoT systems on the new universal training board developed at SibGUTI. The device integrates all components for networked projects, eliminating manual soldering and connection debugging. This speeds up mastering topics from simple prototypes to multi-controller interactions.

Board Components and Design

The board includes key elements for lab work and course projects:

• Four buttons with hardware pull-ups for signal input.
• Potentiometer for analog control.
• RGB LED and sound signal generator for visual and audio feedback.
• Light sensor for environment monitoring.
• I2C and 1-Wire buses for connecting external sensors.

All connectors are reinforced, with protection against shorts and short circuits. This minimizes failures typical of breadboards, where connections break with frequent switching.

Standard breadboard solutions require hours for assembly, taking up 30–40% of the semester. The new board provides a ready platform: connect sensors, write code for the microcontroller, and test the network.

Applications in IoT Projects

Real prototypes are developed on the board:

• Smart irrigation systems: 1-Wire humidity sensors coordinate pumps.
• Greenhouse climate control: light and temperature via I2C control ventilation.
• Automated garage: buttons and potentiometer simulate access, RGB indicates status.

In one semester, students master advanced topics—interaction of multiple controllers via network protocols. The board has been tested at SibGUTI and Samsung Innovation Campus, where groups complete project work without hardware delays.

For senior developers, the platform is useful for quick algorithm validation: integrate ESP32 or STM32, set up MQTT or CoAP without soldering. This reduces time-to-prototype from days to hours.

Advantages Over Analogs

Compared to foreign stands (Arduino Shield, Raspberry Pi Hats), the board is optimized for the academic cycle:

| Characteristic | Breadboards | New Board |

|------------------------|-------------------------|----------------------------|

| Assembly Time | 2–4 hours | 0 |

| Connection Reliability | Low (breaks) | High (reinforced connectors)|

| Protection | None | Against shorts |

| Scalability | Limited | I2C/1-Wire for networks |

Hardware readiness allows focusing on firmware: FSM state implementation, interrupt handling, network stack.

Key Points

• Ready integration eliminates 30–50% of time on mechanics, speeding up project iterations.
• Support for multi-device networks: I2C for sensors, 1-Wire for sensor chains.
• Adapted for schools and universities: from basic code to complex protocols in a semester.
• Russian development as an alternative to imported boards, compatible with Samsung programs.
• Easy scaling: add modules without risk to the base circuit.
