ESP-EYE Development Board V2.1

Ever wanted to dabble in face and/or speech recognition? Espressif's ESP-EYE is a miniature ESP32-based development board that combines a digital microphone, ESP32 (of course) with 8 MB PSRAM and 4 MB flash, and a 2 megapixel camera. There's a few buttons and LEDs as well for basic control and configuration.

Unlike some boards, this codebase does not require internet connectivity - you don't have to send video or audio data to 'the cloud' - it's all processed on-chip! The built in demo shows off what it can do:

Plug into a computer USB port and open up a serial port connection at 115,200 baud to the new serial port

Once the red LED is lit, activate the board with the watchword "Hi Lehshin" (in documents they spell it lexin, the x is pronounced as a shh sound)

The red LED will blink - then connect to the new Wi-Fi access point created

Open up a web browser to http://192.168.4.1/face_stream

Point the camera at faces to show off the recognition boxes! Video is about 2 frames per second, not super fast.

Once you get the demo going, check out the source code and ESP development platform to customize your very own DIY voice/speech recognition project.
