ESP32-S3 development board with 2.16 inch AMOLED display
ESP32-S3-Touch-AMOLED-2.16 is a versatile and highly integrated development board equipped with a capacitive touch screen AMOLED. It is based on a powerful dual-core processor ESP32-S3 with Wi-Fi and Bluetooth 5 connectivity. Thanks to the built-in power management chip, 6-axis IMU sensor, dual microphone, and battery power support, this module is an excellent platform for rapid HMI interface development and advanced IoT devices.
Key features
- Powerful dual-core processor ESP32-S3R8 Xtensa 32-bit LX7 with a clock speed of up to 240 MHz.
- Integrated wireless connectivity Wi-Fi 2.4 GHz (802.11 b/g/n) and Bluetooth 5 (LE).
- Large memory capacity: 512 KB SRAM, 384 KB ROM, 8 MB built-in PSRAM and 16 MB external Flash memory.
- Capacitive touch screen AMOLED 2,16 inch (resolution 480 x 480 px, 16,7 million colors).
- Built-in 6-axis IMU sensor QMI8658 (accelerometer and gyroscope) for motion and gesture tracking.
- Dual microphone array with noise reduction and echo cancellation circuit, facilitating voice recognition.
- Power management chip AXP2101 supporting charging and discharging of Li-Po 3,7V batteries (MX1.25 connector).
- Connector USB-C providing convenient programming, power supply, and log reading.
Compact size, huge possibilities
The board is perfect for designing smart home devices that require user interaction (HMI). The module offers the possibility of connecting an external battery, allowing it to operate as a fully independent mobile device.
New generation AMOLED display
The applied AMOLED technology provides a significant advantage over standard LCD screens. The panel features precise backlight control, resulting in excellent detail reproduction, very high contrast, and wide viewing angles. The CO5300 driver and CST9220 touch chip operate based on QSPI and I2C buses, which saves valuable microcontroller IO pins.
