Features

ESP32-S3-Touch-LCD-4.3B is a microcontroller development board with 2.4GHz WiFi and BLE 5 support, integrates high-capacity Flash and PSRAM. Onboard 4.3inch capacitive touch screen can smoothly run GUI programs such as LVGL. Combined with various peripheral interfaces, suitable for the quick development of the HMI and other ESP32-S3 applications

1. Equipped with Xtensa 32-bit LX7 dual-core processor, up to 240MHz main frequency

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, with onboard 16MB Flash and 8MB PSRAM

4. Onboard 4.3inch capacitive touch display, 800×480 resolution, 65K color

5. Supports capacitive touch control via I2C interface, 5-point touch with interrupt support

6. Onboard voltage regulator, supports 7~36V wide range power supply

7. Onboard RTC chip and rechargeable battery to ensure time data is not lost when power loss

8. Onboard CAN, RS485, I2C interface, TF card slot, MX1.25 2P battery header, and digital isolated IO interfaces, etc.

9. Supports passive and active digital input, with bi-directional optocoupler isolation

10. Supports digital output with optocoupler isolation, provides higher driving capability with up to 450mA sinking current

11. Onboard LED indicators for indicating the power and battery recharging status

12. Supports flexible clock, module power supply independent setting and other controls to realize low power consumption in different scenarios

Application Scenarios

IPS Display Panel
