Official IoT Development Board with 1.14-Inch Colour Screen for Graphical Programming

This official IoT development board suite delivers a practical hardware platform designed for use with graphical programming environments, significantly lowering the barrier to entry for electronics and Internet of Things projects. It integrates a clear visual interface, multiple connectivity options, and essential input/output components into a single, ready-to-use unit. Supplied as a complete suite, it requires only a 5V power source and a computer with the appropriate software to begin prototyping, making it suitable for educational settings, workshops, or hobbyist experimentation where ease of use and immediate functionality are priorities.

Features and Construction

The board's design focuses on providing core functionalities that are commonly required in beginner and intermediate-level IoT applications, all accessible without the need for additional circuitry. Its construction centres on reliable integration of these features onto a PC-based board.

Material and Build

The development board is built on a substrate made from PC (Polycarbonate), chosen for its structural stability and electrical insulation properties which safely house the sensitive electronic components. The layout incorporates a single Type-C USB port for both power delivery and data communication, simplifying the physical connection. Component placement is designed to allow clear access to the two customisable buttons and the red status LED, facilitating user interaction and system state indication during program execution.

Size and Practical Fit

The most prominent physical feature is the integrated 1.14-inch TFT LCD screen, which has a resolution of 135 by 240 pixels and is driven by an ST7789v2 controller. This provides a compact yet readable display area for showing sensor data, graphical interfaces, or debugging information directly on the board itself. The inclusion of the versatile Grove interface—a connector supporting I2C, general-purpose I/O, and UART signals—allows for the physical expansion of the board's capabilities using a wide ecosystem of plug-and-play modules, effectively managing the board's footprint while extending its utility.

Uses and Placement

This suite is engineered to serve as a central hub for interactive and data-driven projects, bridging the gap between abstract graphical code and tangible hardware outcomes. Its integrated components suggest applications where combining user input, environmental sensing, and visual output is valuable.

Event or Professional Use

In educational or workshop environments, this board can function as a standardised teaching tool for demonstrating IoT principles, sensor integration, and basic HMI (Human-Machine Interface) design. The graphical programming approach allows instructors to focus on conceptual learning rather than syntax. For professional prototyping, the onboard real-time clock (RTC) module, the BM8563, enables the development of time-stamping or scheduled operation applications, while the AXP192 power management unit provides stable voltage regulation for the connected components, supporting reliable proof-of-concept builds.

Everyday Home Use

For hobbyists and makers, this board simplifies the creation of custom home automation devices, interactive art installations, or data loggers. The built-in SPM1423 microphone allows for projects that react to sound or clap detection, such as a voice-activated switch or a noise level monitor. The two programmable buttons and the colour screen enable the building of simple menu-driven controllers or status displays for other smart home devices, all programmable through a drag-and-drop interface without writing traditional code.

Benefits and Buying Value

The value of this development board lies in its consolidation of multiple discrete components into a unified, tested platform, reducing project startup time and complexity. It is supplied as a single, functional suite, meaning the user receives a validated system where the core components are already correctly interfaced.

Reuse and Low Maintenance

As a self-contained unit, the board can be reprogrammed and reused across countless different projects. The use of the standard Grove connector system protects the board's main headers from wear and tear, as modules are plugged into the external Grove cable rather than directly into the board. The PC material offers good durability for a development environment, and the board's design, with its integrated power management, minimises the risk of damage from incorrect wiring compared to breadboard-based assemblies.

Why Choose This Product

This official IoT development board suite is a pragmatic choice for anyone seeking a straightforward path from graphical programming blocks to a working electronic device. It distinguishes itself by including a colour display, a multi-protocol Grove port, and audio input capability as standard features, which often require separate purchases and complex wiring with more basic boards. By providing these in one package with official support, it offers a cohesive and reliable starting point for learning and creating, supported by precise technical components like the ST7789v2 display driver and BM8563 RTC.
