ESP32-C6 development board with round 1.43 inch AMOLED display + case - Waveshare 31905

Description

The Waveshare 31905 development board is designed for wearable devices, compact HMI interfaces and AIoT applications where integration of modern wireless connectivity, touch input and multimedia functions is required. The ESP32-C6 microcontroller with a 32-bit RISC-V architecture and a clock frequency of up to 160 MHz enables the implementation of communication, control and interactive applications.

The board integrates a round 1.43 inch AMOLED display with a resolution of 466 x 466 and support for 16.7 million colors. The display is driven by the CO5300 controller via the QSPI interface, while touch input is handled by the FT6146 controller using I2C communication, allowing efficient use of the microcontroller I/O resources.

The development board supports AI voice command applications thanks to the onboard microphones and audio subsystem, and enables presentation of information, user interfaces and multimedia content on the round AMOLED display.

The design includes a QMI8658 6-axis IMU for motion and orientation detection and a PCF85063 RTC chip for real-time clock functionality. Onboard ES7210 and ES8311 audio chips together with the dual microphone support audio input and output in voice-based applications. The TF card slot allows storage expansion, while the MX1.25 battery connector enables battery-powered operation. The ESP32-C6-Touch-AMOLED-1.43-B version is equipped with a protective case, supporting mobile use and prototype testing.
