May 14, 2026 — by Giorgio Mendoza 10,424 views
M5Stack has introduced the PaperColor, a compact development board built around the ESP32-S3R8 processor and a 4-inch Spectra 6 full-color e-paper display. The platform combines wireless connectivity, onboard sensors, audio hardware, battery operation, and expansion interfaces for low-power IoT and embedded display applications.
The system is based on the ESP32-S3R8 SoC featuring dual Xtensa LX7 cores operating at up to 240 MHz together with 2.4 GHz Wi-Fi support. The board integrates 16MB Flash storage, 8MB PSRAM, and an onboard microSD card slot for expandable storage.

For display hardware, the PaperColor uses a 4-inch Spectra 6 full-color e-paper panel with a 400 × 600 resolution designed for low-power operation without requiring continuous backlighting. For user interaction, the board includes three programmable buttons, a dedicated power button, two RGB LEDs, and an infrared emitter.

No operating system info? Programmable in micropython?
wait is this the 90 dollar super colorful art spectra 6 screen that takes longer to refresh BUT has 6 full deep real.colors or whatever? i wanted a pinzero with this but ya if this has community apps ill get this instead
For anyone reading this who, like myself, has never worked with e-paper displays before, just be aware that whenever the screen content changes, it goes through 10 to 15 seconds of attention-grabbing flashing, so it’s best suited for displaying content that doesn’t change very frequently.
And the “full-color” display really is, as Zachary mentioned, just six specific colors (red, green, blue, yellow, black, and white). To get different values of these colors, or to blend between them, requires dithering (which can be very noticeable at close range).
That said, it’s a nice compact package, crammed with features.
I bought one and it even takes close to 30 seconds for the UserDemo to finish updating the screen. This really seriously limits the usability. I have all sensor data I want to refresh regularly, but every 5 minutes an update means 30 seconds ‘out of order’. The delay is too long and the colors on mine are dull also. So know what you buy it for. I have regrets.
