Product Overview

The ESP32-S3-PhotoPainter is an e-Paper AIoT photo frame, equipped with ESP32-S3 microcontroller, which supports dual-mode Wi-Fi and BLE communication. It features a 7.3inch e-Paper screen with low power consumption, making it suitable for portable devices and long-battery-life scenarios. It integrates an RTC real-time clock, an SHTC3 temperature and humidity sensor, a TF card slot, a low-power audio codec chip circuit, and a lithium battery charge/discharge management circuit.

Features

• Equipped with high-performance Xtensa 32-bit LX7 dual-core processor, up to 240MHz main frequency
• Supports 2.4 GHz Wi-Fi and Bluetooth 5 (LE), with onboard internal antenna
• Built-in 512 KB SRAM and 384 KB ROM, with stacked integrated 16 MB Flash and 8 MB PSRAM
• Onboard audio codec chip, supports voice capture and playback, enabling AI voice interaction applications
• The screen uses E Ink Spectra 6 (E6) technology, supporting high-contrast, high-saturation color display effects
• Six primary colors use dithering technology to produce full-color images
• Low overall power consumption, drawing power essentially only during refresh
• Large-capacity lithium battery paired with a power-saving circuit; one charge can support thousands of refreshes (when high-power devices such as speakers are not connected externally)
• Onboard PCF85063 RTC real-time clock and SHTC3 temperature and humidity sensor, enabling precise RTC time management and temperature and humidity monitoring
• Simple solid wood photo frame, elegant and attractive
• Rotating stand and hook, allowing unrestricted usage scenarios
• Open source, freely customizable functions
