LORDWORLD ESP32-S3 7 inch 800×480 65K capacitive touch development board

ESP32-S3 7-inch touch development board

This LORDWORLD board combines an Xtensa 32-bit LX7 dual-core processor running up to 240 MHz with a 7-inch capacitive display at 800×480 resolution and 65K colours. It targets makers and engineers building IoT edge devices that need local graphics, touch input and wireless connectivity in a single module. The board includes 512 KB SRAM, 384 KB ROM, 8 MB Flash and 8 MB PSRAM for application code and buffers.

Check power and interface needs before ordering

The module communicates over 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 LE using an onboard antenna. It exposes CAN, RS485 and I2C interfaces plus a micro SD card slot and a full-speed USB serial port for programming and debug. Verify that your host can supply the required voltage and that your enclosure accommodates the exposed connectors and the display bezel.

Sustained load behaviour with flexible clock control

Under continuous operation the dual-core processor can scale its clock and the module power supply can be set independently to reduce draw. The 5-point capacitive touch controller operates over I2C with interrupt support, so the CPU is not polled during idle periods. Large frame buffers in PSRAM and Flash let the graphics pipeline run without frequent memory thrashing during long rendering tasks.
