What is it?

SIKTEC-EPD is a high grade and professionally made E-Ink / E-Paper Display module. The module is designed to be controlled by any MCU and most of the popular dev boards. The EPD module has dedicated SRAM, MicroSD socket and even a high quality multi directional switch. All of those are easily integrated with the open source SIKTEC libraries that provides excellent examples which have been tested extensively on several physical boards. SIKTEC EPD modules are 3.3v / 5v logic compatible and has the IOREF pin which is commonly used in the Arduino ecosystem. The module has a 2.54 pitch Breadboard compatible header and JST PH2.0mm back connectors for users who prefer wire to board connections which facilitate the integration of the module to your projects.

Why did you make it?

EPDs are Cool! They give a unique feel to projects and has great characteristics which are useful for application who requires low power consumption displays who can be completely turn off and retain the displayed screen. The applications are very wide, you can find them on E-readers, Tickers, Tablets, Smart tags, Smart picture frames, door sign and many more. I made it as a "all you need" package that integrates the 4 required elements in one module 4.2 Inch EPD - High quality EPD Display (3 Variants - check the product sheet). SRAM (256kbit) - The drawing buffer. Don't use your precious MCU RAM. MicroSD - For Storage (Bitmaps and more). MDS - Multi Directional Switch is useful for user input.

The EPD Module Features:

• High quality 4.2’’ E-Paper display (3 drivers available all supported by the libraries).
• Onboard Microchip 256Kbit SRAM for display drawing – Run on any microcontroller.
• MicroSD Card slot – fully integrated.
• Multi Directional Switch – High quality and debounced with optional interrupt trigger.
• 4 Pin SPI to control the Module – Fully managed by the SIKTEC libraries.
• 3.3/5V Logic tolerant (SD and EPD) – Has optional IOREF Pin.
• 2.54 Breadboard compatible header & JST PH2.0mm connectors.
• Arduino Lib Manager & PlatformIO Libraries - Robust and well documented libraries and examples.
• SIKTEC-EPDs libraries are Adafruit_GFX Compatible. 4 Mounting Holes (2.5mm) – M2 screws and mounting spacers included.

The shield supports SIKTEC Libraries and Example codes – All examples can be downloaded from GitHub: https://github.com/siktec-lab/SIKTEC-EPD. Or install using the Arduino / PlatformIO IDE Library Manager.

Choose Your Model:

*1) White, Light Gray, Dark Gray, Black.

*2) Partial refresh is supported – Not directly when using the SIKTEC-EPD libraries – It will be implemented soon. For implementing and controlling the EPDs in “Partial Refresh Mode” please refer the Driver IC datasheet (Also available in SIKTEC-EPD repository).

*3) Real life Measurements: room temperature (22°C), 18Mhz SPI Clock, 5V Vin, 3.3V IOREF, ESP32 WROOM using the SIKTEC-EPD Library.
