LORDWORLD 2.9inch Touch E-Paper Module 296×128 development board
A 2.9inch capacitive touch e-paper display with 296×128 resolution, five-point touch, ultra-low power use and SPI or I2C interface for Raspberry Pi Pico development
- 9 inch capacitive touch ePaper display with 296×128 resolution
- 5-point touch support with user-defined wakeup gesture for interactive control
- No backlight retains last displayed content even when powered down
- Ultra low power consumption requires energy only during screen refresh cycles
- SPI and I2C interfaces minimise IO pin usage on development boards
Compact e-paper touch module
The LORDWORLD 2.9inch Touch E-Paper Module is a development board designed for makers building low-power IoT edge devices. Its 296×128 pixel display and five-point capacitive touch input suit projects needing a readable, interactive surface without constant power draw.
SPI and I2C interface flexibility
The board communicates over SPI or I2C, demanding minimal GPIO pins from a host controller such as a Raspberry Pi Pico. It requires no backlight, freeing power budget and enclosure space while retaining the last shown image indefinitely after supply removal.
296×128 resolution with partial refresh
The 2.9 inch panel handles monochrome graphics and text updates efficiently through partial refresh support. It is not suited to video-rate animation or colour-rich interfaces, and its ultra-low consumption only applies during static display periods.

商品問答
How long can the 296×128 e-paper panel retain its image after power is removed?
The display keeps showing the last content for a long time even when powered down because it has no backlight and only draws power during a refresh.
How much heat or noise does the module produce during continuous operation?
It generates virtually no heat and no audible noise since power is only needed for refreshing the screen.
Which host board and software environment are required to use the SPI or I2C interface?
Development resources and examples are provided for Raspberry Pi Pico using C/C++ and MicroPython.
