This compact driver board is a microcontroller development board with a 60-pin e-ink interface. Hardware-wise, it uses the ESP32-S3-WROOM-2-N32R16V module, equipped with an Xtensa 32-bit LX7 dual-core processor with a clock speed of up to 240MHz. It features 512KB SRAM (TCM), 16MB PSRAM, and 32MB Flash, supporting Wi-Fi and BLE dual-mode communication. Integrated components include a Micro SD card slot, a low-power audio codec chip, a high-efficiency charge/discharge management chip ETA6098, and an MX1.25 lithium battery interface. Onboard CH343 serial port and CH334 USB hub chips allow for simultaneous USB and UART use and development via a single Type-C interface. Multiple external pin headers provide compatibility with various peripheral devices, making it easy to use.

In terms of software, you can choose development environments such as Arduino and ESP-IDF for development, which makes it easy and quick to get started and apply it to products.

Main features：

E Ink Spectra 6 is a newly launched full-color e-paper technology that injects new vitality into the e-paper field with its superior color performance, high resolution, and excellent contrast. The use of red, yellow, and blue color gradations provides more possibilities for color display. High contrast and high saturation make images clearer and colors brighter.

More advanced parameters

With a resolution increased to 200ppi, more lenient operating temperature requirements, shorter screen refresh rates, and greater energy efficiency, it aligns with ESG energy conservation and carbon reduction trends.

Innovative Micro-Cup Full-Color Technology Platform

The colors are vibrant and saturated, created by combining six primary colors—white, red, yellow, and blue—using a color mixing technique (dithering) to produce full-color images.

Advantages of e-ink screens

E-ink displays use "microcapsule electrophoresis display" technology to show images. Its working principle involves charged nanoparticles suspended in a liquid migrating under the influence of an electric field, reflecting ambient light to create a display effect similar to traditional printed paper. E-ink displays can clearly display images under ambient light such as artificial light and natural light, without backlighting, and have a viewing angle of almost 180°. Due to its display quality comparable to traditional paper, it is often used in applications such as e-readers.

Supports ESP-IDF and Arduino

It comes with a complete SDK and open-source tutorials, making it easy to get started and quickly embedded into applications.
