3.52 inch e-paper raw panel development board with 40-pin GPIO header

LORDWORLD

LORDWORLD 3.52inch E-Paper Raw Panel development board

SKU CH-R3Z0-0T58J

A 3.52inch e-paper raw panel with a 40PIN GPIO header for Raspberry Pi and Jetson Nano, SPI interface, onboard voltage translation for 3.3V/5V MCUs.

  • Standard Raspberry Pi 40PIN GPIO header fits Pi series and Jetson Nano directly
  • No backlight retains last image indefinitely after power is removed
  • Ultra-low power draw needs energy only during screen refresh cycles
  • Onboard voltage translator enables safe 3.3 V and 5 V MCU connections
  • SPI interface links to Raspberry Pi, Arduino, STM32 with online wiki resources

Target Platforms

This 3.52inch raw e-paper panel mounts directly onto the standard Raspberry Pi 40PIN GPIO header and also works with Jetson Nano boards. It is intended for developers and hobbyists building low-power display projects that need persistent visuals without constant energy draw.

Operational Benefits

The lack of a backlight means the last image remains visible indefinitely after power is removed. Ultra-low consumption draws current only during refresh cycles, while the onboard voltage translator allows safe connection to both 3.3V and 5V microcontrollers such as Arduino or STM32 via the SPI interface.

Interface Constraints

Communication relies on the SPI bus, which limits update speed compared to parallel or video interfaces and makes the panel unsuitable for video or rapid animation. The raw panel ships without an integrated controller board, so users must handle driving waveforms and timing in their own firmware.

Perguntas sobre este artigo

Will the 3.52inch E-Paper panel itself degrade or need replacing after many refresh cycles?

The raw panel has no backlight and retains its last image without power. Ultra-low consumption means power is only drawn during refresh, so the panel is designed for long-term use without scheduled replacement.

What limits continuous operation when the board is driven via the 40PIN GPIO header on a Raspberry Pi?

The SPI interface and onboard voltage translator handle 3.3V and 5V logic. The practical limit is the e-paper refresh rate; the board draws negligible power between updates, so sustained use is constrained by how often you refresh the 3.52inch display.

How much heat or noise does the development board produce when left running all day?

With no backlight and ultra-low power consumption — only drawing current during SPI refresh cycles — the board generates no audible noise and negligible heat during continuous operation.
