M5Stack M5Paper Color ESP32S3 Dev Kit (600x400, 4" SPECTRA 6 eInk)
M5Stack PaperColor is a full-color ESP32-S3 e-paper development kit designed for low-power visual interfaces. It combines an ESP32-S3R8 controller with 16MB Flash, 8MB PSRAM, and a 4-inch Spectra 6 E Ink display with 400 x 600 resolution, making it a strong fit for information panels, desktop dashboards, smart signage, and other embedded display projects where readability and standby efficiency matter.
This M5Stack board also integrates a practical interaction stack: 3 user buttons, a power key, ES8311 audio codec, ES7210 MEMS microphone with AEC, a 1W speaker, SHT40 temperature and humidity sensing, RX8130CE RTC, microSD storage, IR transmission, 2 RGB LEDs, and an HY2.0-4P expansion port. Paired with the onboard M5PM1 power management system and a 1250mAh battery, M5Stack PaperColor is well suited to portable or always-on IoT display applications.

FAQ
What is the difference between M5Stack PaperColor and M5PaperS3?
M5Stack PaperColor focuses on a 4-inch full-color Spectra 6 e-paper experience, which is a better fit for low-power visual signage and colorful status panels. If you prefer a larger touch-capable e-paper development platform, you can also check the related M5PaperS3 product page.
Can I develop M5Stack PaperColor with Arduino or PlatformIO?
Yes. M5Stack provides an official Arduino quick start, and the documentation also includes a ready PlatformIO environment example. The official M5Unified, M5GFX, and M5PM1 libraries are the main software resources for getting started.
Is M5Stack PaperColor suitable for battery-powered always-on projects?
Yes, especially for projects with mostly static content. The official standby current is 92.53uA, which makes M5Stack PaperColor attractive for low-power dashboards, electronic signage, and portable display terminals. As with other e-paper products, refresh is slower than LCD, so it is best used for information that changes periodically rather than continuously.
How do I enter firmware download mode?
Connect the board through USB Type-C, then press and hold the side reset button while flashing firmware. The official product documentation includes the same operation guidance for download mode and power control.
