M5STACK｜ESP32-S3｜4" FULL-COLOR E-PAPER

M5Stack PaperColor ESP32-S3 4" Full-Color E-Paper Development Kit (C151)

PaperColor is a development board with a 4" E Ink Spectra 6 full-color e-paper display (400 × 600), built around the ESP32-S3R8 with 16MB Flash / 8MB PSRAM and 2.4GHz Wi-Fi. It integrates an ES8311 audio codec, a MEMS microphone with AEC echo cancellation and a 1W speaker, plus an SHT40 temperature and humidity sensor, RTC, microSD, IR emitter, RGB LEDs and an HY2.0-4P port. With a built-in 1250mAh battery and M5PM1 power management, it suits photo frames, information displays, voice terminals and environmental monitoring displays.

What is PaperColor?

PaperColor combines a full-color e-paper display, ESP32-S3, audio, sensors and a battery into a palm-sized device, ready to program with UiFlow2 or Arduino IDE out of the box. The e-paper image stays visible without power, and with low standby consumption it is ideal for content that is displayed for long periods but updated infrequently.

M5Stack PaperColor features: 4-inch full-color e-paper, buttons, speaker, microphone, IR, RGB LED, USB-C, microSD

PaperColor features and interfaces

Note on refresh time: each full-color e-paper refresh takes about 15-30 seconds, depending on the color distribution. It is suited to static or infrequently updated content, not video or fast animation.

Key Features

4" E Ink Spectra 6 full-color e-paper

400 × 600 resolution, low power and high visibility; the image remains after power-off.

ESP32-S3 with Wi-Fi

ESP32-S3R8 dual-core 240MHz, 16MB Flash + 8MB Octal PSRAM and 2.4GHz Wi-Fi to fetch data and update the display.

Voice interaction

ES8311 codec and ES7210 ADC with a MEMS microphone and AEC; an AW8737A amplifier drives a 1W speaker for voice input and playback.

Sensors, expansion and power

SHT40 temperature and humidity sensor, RX8130CE RTC, IR emitter, 2 RGB LEDs, microSD and HY2.0-4P; M5PM1 power management with a 1250mAh battery.

Applications

Smart photo frame

Download photos or artwork from the network and show them in full color.

Information display

Weather, calendar, meeting room status, price labels and other info panels.

Voice terminal

Use the microphone and speaker for voice prompts or voice control.

Environmental display

Log and display data from the built-in temperature and humidity sensor.
