Description

ESP32-S3-Touch-LCD-4.3C in the standard version without case integrates the ESP32-S3 microcontroller with a 4.3-inch capacitive IPS display with 800 x 480 resolution and an onboard audio module supporting sound recording and playback. The design combines display, touch, and voice interaction, enabling development of advanced HMI terminals, control panels, and AI-enabled IoT devices.

The dual-core Xtensa LX7 processor operating up to 240 MHz provides high computing performance. The board includes 16 MB Flash and 8 MB PSRAM, enabling support for advanced graphical interfaces, including those based on LVGL. Wireless connectivity includes 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 LE with onboard antenna.

The IPS display provides a 160° wide viewing angle and supports 5-point capacitive touch via I2C interface with interrupt capability. The ES8311 audio codec together with the ES7210 echo cancellation circuit and two microphones enables implementation of voice control and bidirectional audio communication.

The board provides industrial-grade interfaces, including optocoupler-isolated digital inputs and outputs. Digital inputs support 5 - 36 V signals in passive and active modes (NPN/PNP). Open-drain digital outputs allow control of loads up to 450 mA per channel. Power supply range is 7 - 36 V DC, and the onboard voltage regulator together with the RTC circuit and CR927 battery holder maintains time settings during power loss.

Available onboard interfaces include USB Type-C, TF card slot, 3.7 V lithium battery connector (MX1.25 2PIN), screw terminals, I2C interface, and selectable 5 V or 3.3 V VOUT configured by onboard resistor. The design supports integration in embedded systems and industrial installations.
