This article compares both devices to help you make an informed decision.
M5Paper: A Versatile E-Ink Device with a Large Screen
The M5Paper offers a 4.7-inch e-ink display with a resolution of 540 x 960 pixels and 16 levels of grayscale. It delivers a paper-like reading experience, perfect for long reading sessions without causing eye strain.
Powered by ESP32-D0WD for Smooth Performance
The ESP32-D0WD microcontroller ensures efficient performance and low power usage. The GT911 touch panel adds two-point capacitive touch and supports gesture control, making it easy to interact with.
Energy-Efficient E-Ink Display
A key feature of the M5Paper is its low power consumption. The e-ink display retains images even when the device is off, extending battery life for frequent use.
Built-in Sensors and Expansion Options
The M5Paper also integrates several sensors and interfaces:
- SHT30 temperature and humidity sensor
- FM24C02 storage chip
- BM8563 real-time clock (RTC)
It includes three HY2.0-4P ports, allowing easy sensor expansion for IoT and smart home projects.
Applications of M5Paper
The M5Paper works well for:
- Electronic reading: Mimics the feel of a real book.
- Smart home control: Manage devices with touch control.
- Outdoor use: The e-ink display is readable even in sunlight.
- Education tools: Supports touch and handwritten operations.
M5Stack Core Ink: Compact and Portable E-Ink Display
The M5Stack Core Ink features a smaller 1.54-inch black-and-white e-ink screen with 200 x 200 pixels. Although smaller, it offers many of the same benefits as the M5Paper, including low power consumption and easy readability.
Powered by ESP32-PICO-D4 for Efficient Performance
The Core Ink runs on the ESP32-PICO-D4 microcontroller, providing stable performance and reliable wireless connectivity. It includes:
- Multi-function button
- Physical button
- Integrated LED and buzzer
The 390mAh LiPo battery and BM8563 RTC ensure accurate timing and deep sleep capabilities for extended battery life.
Compact and Energy-Efficient Design
The lightweight build makes the Core Ink ideal for mobile data logging and other portable applications. The e-ink screen retains images even when powered off, saving battery life during frequent updates.
Expansion Ports for Prototyping
The Core Ink supports additional sensors and hardware through:
- HY2.0-4P
- M-BUS interface
- HAT expansion port
These interfaces make it perfect for IoT concept prototypes and other creative projects.
