M5Stack Paper Colour

The M5Stack Paper Colour combines a vibrant 4" full-colour ePaper display with wireless connectivity, audio capabilities, onboard sensors, and battery power, making it ideal for smart signage, information displays, environmental monitoring, and interactive IoT projects.

The M5Stack Paper Colour is a development board featuring a 4" ePaper Spectra 6 full-colour e-paper display with a resolution of 400x600, offering both low power consumption and high visibility. It is built around an integrated ESP32-S3R8 core with 16MB Flash and 8MB PSRAM, and supports 2.4 GHz Wi-Fi wireless communication. The board incorporates a complete human-machine interaction system, including three programmable buttons, an audio system based on the ES8311 audio codec, a MEMS microphone with AEC echo cancellation, and a speaker driven by an AW8737A amplifier — enabling high-quality voice capture and audio playback. In terms of expanded functionality, the board integrates an SHT40 temperature and humidity sensor, RX8130CE real-time clock, microSD card slot, infrared emitter, two RGB LEDs, and an HY2.0-4P expansion interface. Combined with the M5PM1 multi-stage power management system and a 1250mAh battery, it enables long-lasting, low-power operation. Suitable for IoT and embedded applications such as electronic signage, voice interaction terminals, environmental monitoring instruments, and art display installations.
