Official IoT Development Board Graphical Programming Suite with 1.14-Inch Colour Display

This graphical programming suite offers a streamlined approach to Internet of Things project development, combining hardware and software in one package. The central development board features a 1.14-inch colour TFT LCD screen with 135*240 pixel resolution, driven by an ST7789v2 controller, providing clear visual feedback for your applications. Power is supplied through a USB Type-C port rated for 5V@500mA, making it compatible with standard USB power sources and computer ports. The integrated Grove connector system simplifies peripheral attachment by supporting I2C, digital I/O, and UART communication protocols in one interface. This eliminates the need for complex wiring when connecting sensors, actuators, and other modules commonly used in IoT prototyping.

Features and Construction

The board incorporates several key components designed specifically for IoT applications, housed within a PC plastic enclosure that provides protection and structure.

Material and Build

The development board uses PC (polycarbonate) plastic for its housing material, creating a durable shell for the electronic components. This material choice provides impact resistance and protects the internal circuitry during prototyping and testing. The board's construction includes surface-mounted components with the AXP192 power management unit handling voltage regulation and distribution throughout the system. This ensures stable operation of the display, microphone, and connected peripherals. The BM8563 real-time clock module maintains accurate timekeeping even when the main power is disconnected, which is essential for timestamping sensor data in IoT applications.

Size and Practical Fit

While exact dimensional specifications are not provided in the source material, the inclusion of a 1.14-inch display suggests a compact form factor suitable for embedded applications. The Grove connector's standardised interface allows connection to a wide range of compatible sensors without requiring additional adapter boards. Two customisable buttons provide physical input options for user interaction with projects, while a single red LED offers visual status indication. The USB Type-C port serves dual purposes for both programming and power delivery, reducing the need for multiple cables in your workspace.

Uses and Placement

This suite supports various IoT development scenarios, from educational environments to professional prototyping, with its graphical programming approach lowering the technical barrier to entry.

Event or Professional Use

In professional settings, the board can serve as a rapid prototyping tool for IoT concepts before moving to custom PCB designs. The integrated RTC module makes it suitable for time-sensitive applications like environmental monitoring systems that log data at specific intervals. The microphone enables audio-based triggering or sound level monitoring projects, while the Grove system allows quick integration of temperature, humidity, motion, or light sensors. The graphical programming environment accelerates development cycles by allowing functional testing without writing extensive code, making it valuable for proof-of-concept demonstrations and client presentations.

Everyday Home Use

For hobbyists and educators, this suite facilitates home automation projects like smart plant monitors, security alerts, or weather stations. The colour display provides immediate visual feedback, showing sensor readings, system status, or custom interfaces without needing a separate computer monitor. The two programmable buttons can control connected devices, toggle between display modes, or activate specific functions in your IoT applications. With 5V power requirements, the board can be powered from common sources like USB power banks, making it portable for temporary installations or demonstrations outside a traditional workshop environment.

Benefits and Buying Value

The integrated nature of this suite provides several practical advantages over assembling components separately, particularly for those new to IoT development or graphical programming approaches.

Reuse and Low Maintenance

The board's standardised interfaces support repeated use across multiple projects without requiring permanent modifications. The Grove connector system allows sensors and modules to be easily swapped between applications, while the USB Type-C connection ensures compatibility with current computer hardware. The PC plastic housing protects components from physical damage during handling and storage between projects. Since the suite includes both hardware and graphical programming software, you maintain a consistent development environment that reduces setup time for future IoT initiatives.

Why Choose This Product

This graphical programming suite combines several commonly needed IoT components into one verified system, eliminating compatibility concerns between separate purchases. The inclusion of both input (microphone, buttons) and output (display, LED) elements on a single board provides immediate functionality without additional purchases. The integrated RTC and power management units address specific IoT requirements that generic development boards often lack. For those seeking to develop IoT applications with visual interfaces without delving into complex display driver programming, the pre-configured colour TFT screen represents a significant time-saving advantage.
