ESP32-S3 PhotoPainter 7.3 Inch E-Paper Wooden Picture Frame

The ESP32-S3 PhotoPainter is an E-Ink picture frame featuring an integrated ESP32-S3 microcontroller and a 7.3-inch full-color display based on E Ink Spectra 6 (E6) technology. The display offers a resolution of 800 × 480 pixels and renders images in six primary colors, with dithering technology producing vibrant and color-saturated displays. The powerful Xtensa 32-bit LX7 Dual-Core processor operates at up to 240 MHz and is complemented by 16 MB of Flash and 8 MB of PSRAM. Wireless connectivity is provided via 2.4 GHz Wi-Fi and Bluetooth 5 (LE) with an onboard antenna. Onboard components include an ES7210 ADC and an ES8311 DAC audio chip, a dual-microphone array, and a speaker connection, enabling AI-driven voice interaction and text-to-image functions. A PCF85063 RTC chip ensures precise timekeeping, while the SHTC3 sensor measures ambient temperature and humidity. The picture frame is encased in a sleek solid wood frame with a white mat and features a rotatable stand and a wall mount on the back. A TF card slot allows for data expansion using FAT32-formatted storage cards. Optionally, a 3.7V lithium battery can be connected, enabling thousands of image changes without external power thanks to the low-power E-Ink technology and integrated power-saving circuit. The source code is open-source and allows for customization of functionality.
