1.28-Inch Double Eye Round Touch LCD Display with ESP32-S3

This development board combines two integrated 1.28-inch IPS touch displays with a resolution of 240×240 pixels and 65,000 colors, ideally suited for interactive user interfaces or animated “eyes” in robotics projects. The powerful ESP32-S3 microcontroller with a dual-core LX7 processor achieves up to 240 MHz and features 16 MB Flash and 8 MB PSRAM for extensive software projects. Wireless connectivity is provided through 2.4 GHz Wi-Fi and Bluetooth LE. An integrated ES8311 audio codec and an ES7210 ADC enable the playback and recording of audio signals; a microphone is integrated, and an 8 Ω speaker is included. A charging and protection circuit allows direct operation on a 3.7 V lithium cell; alternatively, a USB-C port is available for power supply. A microSD card slot provides storage for images, audio, or log data. A JST-SH-14-pin header allows the use of UART, I2C, and additional GPIO pins for external sensors. FPC connectors (14-pin and 18-pin) connect the touch displays and enable a compact design. An IPEX connector for an external antenna can optionally be retrofitted. With two touch displays, audio support, wireless communication, and battery operation, the board is ideal for HMI prototypes, robot controls, and interactive IoT displays. Included with the board are an SH1.0-14-pin cable, an FFC-18-pin cable, and the speaker.
