Description
The ESP32-S3-PhotoPainter is an e-Paper AIoT photo frame, equipped with ESP32-S3 microcontroller with Wi-Fi and BLE communication support. Onboard 7.3inch e-paper display, features ultra-low power consumption, suitable for portable devices and long-battery-life scenarios. Integrated with an RTC chip, SHTC3 temperature and humidity sensor, TF card slot, low-power audio codec chip circuit, and Lithium battery recharge management circuit.
Features
- Adopts high-performance Xtensa 32-bit LX7 dual-core processor, up to 240MHz main frequency
- Supports 2.4GHz Wi-Fi and Bluetooth 5 (LE), with onboard antenna
- Built-in 512KB SRAM, 384KB ROM, with integrated 16MB Flash and 8MB PSRAM
- Onboard audio encoder and decoder chips, supports voice capture and playback, enabling AI speech interaction applications
- Adopts E Ink Spectra 6 (E6) technology, features high contrast and high color saturation
- Supports six primary colors and employs Dithering technology to create vivid and saturated full color images
- Ultra-low power consumption, basically power is only required for refreshing
- Large capacity Lithium battery (optional), onboard power saving circuit, enabling thousands of refreshes on a single charge (without external speaker or other high-power peripherals)
- Onboard PCF85063 RTC chip and SHTC3 temperature & humidity sensor for accurate RTC management and environmental monitoring
- Simple solid wood photo frame, elegant and beautiful
- Rotatable stand and hook hanger on the back, not limited to usage scenarios
- Open source code, more freedom to customize functions
