1.54 inch ePaper display 200x200, SPI, black/white

This 1.54 inch e-paper display module offers a resolution of 200 × 200 pixels with a sharp black and white image. It is ideal for low-power applications where content is updated occasionally and must remain visible without continuous power.

E-paper technology allows the display to retain its image even when power is removed. Power is only required during refresh, making this module perfect for battery-powered and energy-efficient designs.

The display communicates via SPI and includes onboard voltage generation circuitry, eliminating the need for external high-voltage components.

Features

• 1.54 inch e-paper display
• Resolution: 200 × 200 pixels
• Colors: black and white
• SPI interface
• Ultra-low power consumption
• Image retention without power
• Wide viewing angle
• Integrated charge pump circuitry
• Compatible with Arduino, ESP32, RP2040 and similar platforms

Pinout

• VCC: 3.3V power supply
• GND: ground
• SDI: SPI MOSI (data input)
• SCLK: SPI clock
• CS: chip select
• D/C: data / command control
• RST: reset
• BUSY: busy status output (low during refresh)

Electrical Notes: This display operates at 3.3V logic levels. Direct connection to 5V microcontrollers (such as Arduino Uno) requires level shifting.

Library Support: This display is based on common e-paper controller families such as SSD1608 or SSD1681, widely used in 1.54 inch 200 × 200 monochrome panels.

Recommended libraries:

• GxEPD2 (primary library)
• Adafruit GFX (graphics support)

Library source:
https://github.com/ZinggJM/GxEPD2

Getting Started

• Install the GxEPD2 library via Arduino Library Manager
• Install Adafruit GFX
• Connect the display using SPI
• Select a compatible 1.54 inch 200 × 200 display driver
• Upload an example sketch and adjust pin assignments

Example Wiring (ESP32)

• VCC → 3.3V
• GND → GND
• SDI → GPIO23 (MOSI)
• SCLK → GPIO18 (SCK)
• CS → GPIO5
• D/C → GPIO17
• RST → GPIO16
• BUSY → GPIO4

Usage Notes

• Typical refresh time: 2 to 5 seconds
• Supports partial updates (faster refresh for small changes)
• Avoid excessive full refresh cycles to prolong display life
• BUSY pin must be connected for proper operation
• If the display becomes unresponsive, power cycle the module

Compatibility

This display is compatible with many 1.54 inch monochrome SPI e-paper modules using SSD1608 or SSD1681 controllers. It is functionally similar to common Waveshare 1.54 inch displays supported by the GxEPD2 library.

If one driver does not work, try alternative 1.54 inch 200 × 200 drivers within the library.

Applications

• Electronic labels and price tags
• Low-power status displays
• IoT dashboards
• Data logging displays
• Battery-powered projects
