ESP32-S3 4.3" Capacitive Touch Display Development Board with Case, 16MB Flash, LVGL Support, Rich IO Expansion

ESP32-S3-Touch-LCD-4.3B is a microcontroller development board supporting 2.4GHz Wi-Fi and BLE 5. It features high-capacity Flash and PSRAM, an onboard 4.3-inch LCD capacitive touchscreen capable of smoothly running GUI programs such as LVGL, and multiple peripheral interfaces for rapid development of ESP32-S3-based HMI applications.

Key Features:

1. Powered by a high-performance Xtensa 32-bit LX7 dual-core processor, running at up to 240MHz
2. Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE), with onboard antenna
3. Built-in 512KB SRAM and 384KB ROM, stacked with 16MB Flash and 8MB PSRAM
4. Onboard 4.3-inch LCD capacitive touchscreen 800 × 480 resolution, 65K colors
5. Supports I2C interface capacitive touch control 5-point touch, supports interrupt
6. Onboard voltage regulator chip supports wide voltage power supply from 736V
7. Onboard RTC chip and rechargeable battery enables time retention during power loss
8. Onboard CAN, RS485, I2C interfaces, Micro SD card slot, GH1.25 2P battery connector, and digital isolation I/O resources
9. Inputs with bidirectional optocoupler isolation supports both passive and active switch signal inputs; active source supports positive and negative voltage
10. Outputs with optocoupler isolation stronger driving capability, sink current up to 450mA (MAX)
11. External LED indicators convenient for checking power and battery charging status
12. Supports flexible clock and independent module power settings for precise control, enabling low-power operation across multiple scenarios
