ESP32-S3 Touch AMOLED Display 2.16 Inch 480x480

The ESP32-S3 Touch AMOLED Display 2.16 Inch 480x480 is a compact development board from Waveshare featuring an integrated 2.16-inch AMOLED touch display. At its core is the ESP32-S3R8 with a Xtensa 32-bit LX7 Dual-Core processor clocking up to 240 MHz. The board includes 512 KB SRAM, 384 KB ROM, 8 MB PSRAM, and 16 MB external flash memory. The AMOLED display offers a resolution of 480 × 480 pixels with 16.7 million colors, a brightness of 600 cd/m², and a contrast ratio of 100,000:1. The display is driven by the CO5300 controller via QSPI, while the capacitive touchscreen is managed by the CST9220 controller over I2C. Additionally, it integrates a QMI8658 6-axis IMU with accelerometer and gyroscope, an RTC chip, and an AXP2101 power management IC. Two noise-canceling microphones with echo cancellation enable high-quality audio capture for voice recognition. The board supports 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 (LE) via an integrated antenna. Programming and power supply are handled through a USB Type-C port, while an MX1.25 connector allows operation with a 3.7V lithium battery. Additional features include a TF card slot, programmable buttons (PWR, BOOT, GPIO 18), and I2C, UART, and USB interfaces. Development is supported via ESP-IDF and Arduino IDE.

Features:

• AMOLED technology offers high contrast, a wide 178° viewing angle, fast response times, and low power consumption.
• Dual-microphone array with integrated echo cancellation enables precise voice recognition and near/far-field wake-up functionality.
• QMI8658 6-axis IMU with accelerometer and gyroscope allows motion gesture detection and step counting.
• AXP2101 power management IC supports efficient battery management with charging and discharging via the MX1.25 connector.
• Wireless connectivity via 2.4 GHz Wi-Fi and Bluetooth 5 (LE) with integrated antenna and optional IPEX-1 antenna connector.
• Programming and development supported by ESP-IDF and Arduino IDE with comprehensive tutorials.

Application Examples:

• Compact control panel for smart home systems with touch input and Wi-Fi connectivity.
• Portable device with motion detection and step counting via the integrated IMU sensor.
• Voice-controlled assistant with near and far-field wake-up functionality thanks to the dual-microphone array.
• Status display and data visualization for IoT sensor projects with wireless data transmission.
• Prototyping platform for wearable applications with battery operation and AMOLED display.
