Compact IoT Board with Touch Screen
The LORDWORLD ESP32-S3 development board integrates a 1.83 inch IPS display with a 240 by 284 pixel resolution and 65K colour depth. It embeds an ST7789P display driver and a CST816D capacitive touch controller for direct human-machine interaction. An onboard ES8311 audio codec and ES7210 echo cancellation circuit handle voice input and output. The board supports offline speech recognition and can connect to online AI platforms such as DeepSeek and Doubao.
Makers Building Voice-Enabled Devices
This board suits developers creating portable smart devices that need a touchscreen, audio I/O and wireless connectivity in a small footprint. Battery support allows untethered operation for prototypes or final products. It is not a fit for projects requiring a larger display area, higher resolution graphics, or cellular connectivity. Builders needing multiple high-current GPIO pins or a ruggedised enclosure should evaluate other platforms.
Steady Operation Under Continuous Voice Load
During sustained voice recognition and AI interaction the onboard audio codec and echo cancellation circuit maintain consistent capture quality without buffer overruns. The ESP32-S3 processor manages continuous Wi-Fi or BLE data streams while driving the IPS panel at full refresh. Thermal output remains low enough for enclosed battery-powered enclosures. No throttling or audio artefacts appear during extended sessions.

Questions sur cet article
Does this board need an external power supply or can it run from a battery?
The board supports connecting a battery for independent operation, so it can run without an external supply once a suitable cell is attached.
Will the 240 × 284 IPS panel still be readable if I mount it beside older 1.83 inch non-IPS screens?
The IPS panel provides a wide viewing angle and 65K colour depth, giving better off-axis readability and colour consistency than typical older non-IPS modules of the same size.
How can I verify the touch controller and audio codec are functioning after I flash my first sketch?
Run a test sketch that reads the CST816D touch coordinates and plays a tone through the ES8311 codec; successful touch events and audible output confirm both peripherals are working.
