ESP32-S3 development board with 7 inch display

This board combines an Xtensa 32-bit LX7 dual-core processor running up to 240MHz with a built-in 7 inch capacitive touch LCD. The screen delivers 800×480 resolution and 65K colour depth. It targets makers building human-machine interfaces or IoT edge devices that need local graphics and touch input.

Onboard antenna and integrated memory

Wi-Fi 802.11 b/g/n at 2.4 GHz and Bluetooth 5 LE are driven by an onboard antenna, removing the need for external RF parts. The module also includes 512KB SRAM, 384KB ROM, 8MB PSRAM and 8MB Flash so firmware and assets can run without added storage. Five-point capacitive touch with interrupt support arrives over an I2C link.

Peripheral interfaces for rapid HMI prototyping

A range of broken-out interfaces lets developers connect sensors, actuators or communication modules directly to the board. Flexible clock and independent power-supply controls help reduce consumption in battery-powered scenarios. The package suits engineers who need an all-in-one display and wireless platform, while buyers requiring a larger screen or additional GPIO headers must look elsewhere.

商品問答

What component on the board will need replacement if the 5-point capacitive touch layer stops responding?

The capacitive touch layer is integrated with the 7 inch 800×480 display, so the entire display module would need replacement.

What limit appears first when the dual-core Xtensa LX7 runs continuously at 240 MHz with Wi-Fi active?

The onboard 2.4 GHz antenna and 8 MB PSRAM share the same power domain, so thermal throttling or voltage droop on that rail will limit sustained throughput.

How much heat and noise does the board produce when driving the 65K colour LCD and Bluetooth 5 radio all day?

No fan is fitted; the board relies on passive dissipation, so it runs silent and surface temperature rises modestly under continuous load.
