T5 E-Paper 2.7 inch get it now

Overview

LILYGO T5 E-Paper 2.7 inch is an ESP32-based e-paper development board featuring a 2.7-inch Waveshare e-ink display (264 × 176) with ultra-low standby power consumption. Powered by the ESP32 dual-core Xtensa LX6 @ 240 MHz with Wi-Fi and Bluetooth 4.2, the board includes a CP2102 USB-to-serial chip for programming, a MAX98357A I2S amplifier and speaker connector for audio output, a MicroSD card slot, and a battery connector for portable operation. Ideal for IoT display nodes, electronic shelf labels, weather stations, and any application requiring a sunlight-readable, low-power display.

FAQ

• Q. How long does an e-paper screen refresh take? A. A full 2.7-inch e-paper refresh typically takes 2–4 seconds. Partial refresh (if supported) can be faster but may leave ghosting artifacts.

• Q. Does the display retain its image when powered off? A. Yes. E-paper displays are bistable — they retain their last image indefinitely without any power, making them ideal for deep-sleep IoT applications.

• Q. Can I use deep sleep between updates? A. Yes. ESP32 deep sleep current is in the µA range. Use esp_deep_sleep_start() and wake via a timer or GPIO interrupt for extremely long battery life.
