Product description
ESP32-S3-Touch-AMOLED is a development board with a round 1.75" touchscreen and wireless connectivity. The board is based on ESP32-S3 and is suitable for IoT devices, HMI interfaces, portable systems, and applications with voice control and visual interaction.
The board features a 1.75-inch AMOLED display with capacitive touch and a resolution of 466 x 466 pixels. AMOLED technology provides high contrast, wide viewing angles, and fast response time, resulting in clear and vivid image rendering. The touch panel is controlled via I2C while the display uses a QSPI interface, reducing the load on the microcontroller’s I/O resources.
The core is based on the ESP32-S3R8 with a dual-core Xtensa LX7 processor and a clock frequency of up to 240 MHz. The board includes built-in support for Wi-Fi and Bluetooth LE, enabling wireless communication without external modules. The memory configuration includes both 8 MB PSRAM and 16 MB flash memory, providing sufficient capacity for graphics and data processing.
The board also includes several integrated features such as a 6-axis IMU (accelerometer and gyroscope), real-time clock (RTC), dual microphones with support for noise reduction and echo cancellation, and a microSD card slot. This enables the development of advanced systems with sensing, audio, and storage in a compact solution.
Power is supplied via USB-C or through a 3.7 V lithium battery connection with integrated charging management. The board supports development via ESP-IDF and Arduino.
Includes speaker.
