ESP32-S3 3.5" – Touch Screen Module with Camera and Audio
The ESP32-S3-Touch-LCD-3.5 development board features a 3.5-inch capacitive IPS display, power management IC, 6-axis sensor (accelerometer and gyroscope), RTC, and audio codec. Ideal for rapid prototyping and integration into end products, it also offers integrated audio input and output for AI interaction and voice control.
Key Features:
- ESP32-S3R8 Xtensa 32-bit LX7 dual-core processor, clocked up to 240MHz
- Supports 2.4GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) with built-in antenna
- Built-in 512KB SRAM and 384KB ROM, with 8MB PSRAM and 16MB external Flash memory
- USB Type-C connector – increased compatibility and ease of use
- 3.5-inch capacitive IPS touch display with 320×480 pixel resolution (262K colors)
- Built-in display driver ST7796 (SPI) and touch IC FT6336 (I2C)
- Integrated 6-axis IMU QMI8658 (accelerometer and gyroscope) for gesture detection and step counting
- RTC PCF85063 with power from the main Li-ion battery (via AXP2101) and connector for a backup RTC battery
- 3.7V MX1.25 lithium battery charging connector
- Exposed I2C, UART, USB, and GPIO pins for connecting peripherals and debugging
