A compact development module based on the ESP32-S3R8 microcontroller with a dual-core 32-bit Xtensa LX7 processor clocked at up to 240 MHz. The module provides 2.4 GHz Wi-Fi (802.11 b/g/n) and Bluetooth 5 LE wireless connectivity, making it ideal for IoT projects. The board features a 1.8-inch AMOLED touchscreen with a resolution of 368 x 448 pixels, offering 16.7 million colors and a wide viewing angle of 178°, resulting in vivid colors and a clear image.

The CST820 controller, which communicates via the I2C interface, handles the capacitive touch functionality, while the display itself is controlled by the modern CO5300 controller using the QSPI bus. The module is equipped with a rich set of peripherals: a QMI8658 IMU motion sensor (3-axis accelerometer and gyroscope), a PCF85063 RTC real-time clock, an ES8311 audio codec with a microphone and speaker, as well as a TF card slot. Power management is handled by the AXP2101 chip, and the kit includes a 3.7 V lithium battery charged via a USB Type-C port.

Note: The case with a hinged cover facilitates the installation of the module in DIY projects and embedded devices. Available GPIO, UART, I2C, and USB ports allow for flexible expansion of your own designs.
