Description

The ESP32-Touch-LCD-3.5 is designed for projects requiring a touch interface, wireless communication, and audio functionality integrated into a single device. The board is based on the ESP32-WROOM-32 module with a dual-core Xtensa LX6 processor clocked up to 240 MHz, enabling development of IoT applications, HMI interfaces, and control systems.

The capacitive IPS display with a 3.5inch diagonal and 320x480 resolution provides clear visuals and wide viewing angles. The ST7796 display driver and FT6336 touch controller communicate via SPI and I2C respectively, reducing GPIO usage. The onboard ES8311 audio codec, microphone, and speaker enable voice interaction features and Bluetooth audio playback.

The board supports 2.4 GHz Wi-Fi as well as Bluetooth Classic and BLE. The integrated AXP2101 power management IC ensures stable operation, supports battery charging, and manages power consumption. This version is supplied with a 3.7 V lithium battery, enabling portable operation without continuous external power.
