2.66-inch e-Paper Module Product Overview
The Waveshare 2.66-inch e-Paper Module is an electronic paper display module based on "microcapsule electrophoretic display" technology, featuring black and white dual-color display, 296×152 resolution, 2 gray levels, and a viewing angle greater than 170°. The 2.66-inch e-Paper Module requires no backlight and can retain the last displayed content for a long time after power-off. The 2.66-inch e-Paper Module is available in two versions: raw panel (without driver board) and module (with driver board). The module version of the 2.66-inch e-Paper Module features an onboard level shifter compatible with 3.3V and 5V MCU interfaces, supports 3-wire SPI and 4-wire SPI communication, and can connect to Raspberry Pi, Jetson Nano, Sunrise® X3 Pi, Arduino, STM32, and other main control boards. With extremely low power consumption, the 2.66-inch e-Paper Module basically only consumes power during refresh. Partial refresh time is 0.3s, full refresh time is 6s, refresh power consumption is 42.4mW (typ.), and sleep current is <0.01uA (near zero). The 2.66-inch e-Paper Module is suitable for shelf labels, industrial instruments, supermarket price tags, asset equipment labels, electronic shelf labels, conference nameplates, and other display applications.

FAQ
Q: What is the difference between the raw panel and module versions?
A: The 2.66-inch e-Paper Module raw panel version provides only the e-Paper screen at 3.3V, requiring a user-supplied driver circuit. The module version of the 2.66-inch e-Paper Module includes the screen and driver board at 3.3V/5V with an onboard voltage translator, directly connectable to Raspberry Pi, Jetson Nano, Arduino, and STM32 with included example code.
Q: Does it support partial refresh, and what is the refresh time?
A: Yes. For the 2.66-inch e-Paper Module, partial refresh time is typically 0.3s; full refresh time is typically 6s. Partial refresh of the 2.66-inch e-Paper Module is ideal for frequently updating small content areas, such as shelf label price changes.
Q: What is the SPI interface pin definition for the module version?
A: The 2.66-inch e-Paper Module provides an 8-pin SPI control interface: VCC (3.3V/5V), GND, DIN (MOSI), CLK (SCK), CS (chip select, active low), DC (data/command control, high for data, low for command), RST (external reset, active low), BUSY (busy status output, high indicates busy).
Q: How is the power consumption? Is it suitable for battery-powered applications?
A: Typical refresh power of the 2.66-inch e-Paper Module is only 42.4mW, with sleep current below 0.01μA (near zero). The 2.66-inch e-Paper Module retains display content after power-off, making it ideal for battery-powered low-power applications such as electronic price tags and portable information boards.
Q: What host platforms are compatible with the module version?
A: The module version of the 2.66-inch e-Paper Module features an onboard voltage translator compatible with 3.3V and 5V MCU interfaces, directly connectable to Raspberry Pi, Jetson Nano, Sunrise X3 Pi, Arduino, and STM32. Waveshare provides example code for these platforms.
