MCDODO ESP32-S3 2.06inch AMOLED Touch Watch Development Board

DIY Wearable Development Board

This board is a wearable development platform built around the ESP32-S3R8 microcontroller with a 2.06 inch AMOLED capacitive touch display. It integrates a 6-axis IMU, RTC chip, ES8311 audio codec and ES7210 echo cancellation circuit. The dual-core Xtensa LX7 processor runs at up to 240MHz and provides 2.4 GHz Wi-Fi 802.11 b/g/n plus Bluetooth 5 LE connectivity. It is supplied new and requires the user to write firmware for any functionality.

For Developers Building Voice Enabled Wearables

The board suits engineers and hobbyists who want to prototype offline voice recognition, AI speech interaction or audio capture and playback in a watch form factor. Detachable straps allow quick style changes during testing. Buyers expecting a ready to use smartwatch with pre loaded apps or a standard consumer interface should look elsewhere because no application software is included and all features must be programmed from scratch.

Audio Codec and Echo Cancellation Hardware

The onboard ES8311 codec and ES7210 echo cancellation circuit enable direct microphone input and speaker output without extra modules. This hardware supports the offline voice recognition and AI speech interaction highlighted by the manufacturer and also allows access to online large model platforms. The integrated power management IC and RTC chip further reduce the need for external components when building a complete wearable prototype.
