-
M5PaperS3: Upgrades to the ESP32-S3R8, which features an advanced dual-core LX7 processor also at 240 MHz. This newer chip offers improved performance, security features, and support for USB OTG, making it more capable for complex projects
Display and Interaction
Both devices share the same display specifications:
-
Display: A 4.7" E-Ink screen with a resolution of 960x540 pixels, providing excellent readability with low power consumption. However, the interaction capabilities differ:
-
M5Paper V1.1: Includes a capacitive touch screen, but lacks the advanced features of the M5PaperS3.
-
M5PaperS3: Also features a capacitive touch screen but with enhanced capabilities like two-point touch and gesture support through the GT911 touch panel.
-
Memory and Storage
-
M5Paper V1.1: Equipped with 520 KB SRAM, 4MB PSRAM, and 16MB Flash, offering decent memory for basic IoT applications.
-
M5PaperS3: Boasts significantly more memory with 8MB PSRAM, 16MB external Flash, and the added advantage of MicroSD card support for expandable storage, which is crucial for applications requiring data logging or handling large datasets.
Connectivity
-
M5Paper V1.1: Provides Wi-Fi and Bluetooth 4.2 for wireless communication, suitable for most IoT connectivity needs.
-
M5PaperS3: While it offers Wi-Fi, the documentation does not explicitly mention Bluetooth. However, given the ESP32-S3 capabilities, Bluetooth 5.0 support is implied, offering improved speed and range over Bluetooth 4.2.
Battery and Power Management
- M5Paper V1.1: Comes with a 1200 mAh battery, sufficient for many IoT projects but less than the M5PaperS3.
- M5PaperS3: Has a larger 1800 mAh battery, combined with a more sophisticated power management system including an RTC chip (BM8563) for sleep and wake-up functions, providing enhanced battery life and management.
Additional Features
-
M5Paper V1.1: Offers basic features like an ambient light sensor, Grove ports for expansion, and capacitive touch.
-
M5PaperS3: Enhances the feature set with:
-
Gyroscope (BMI270) for motion detection.
-
Onboard Buzzer for audio feedback.
-
Physical Button for power management and device control.
-
Back magnet for mounting on metal surfaces.
-
Hanging hook for easy carrying.
-
USB OTG functionality for connecting external devices.
-
Ideal Applications
-
M5Paper V1.1: Best suited for simple IoT projects where basic display capabilities, touch interaction, and moderate connectivity are required. Ideal for digital signage, basic IoT monitoring, or as an educational tool.
-
M5PaperS3: Tailored for more advanced IoT applications requiring higher resolution displays, more memory, enhanced interaction (touch and gestures), and extended battery life. It's perfect for:
-
Detailed graphics or text display.
-
Projects involving motion detection or vibration feedback.
-
Applications needing USB OTG functionality for data transfer or device control.
-
Advanced IoT monitoring with data logging capabilities.
-
Development Environment
Both devices support Arduino IDE, MicroPython, and ESP-IDF for development. However, the M5PaperS3 also supports UIFlow 2.0 and Platform.IO, providing more options for developers, especially those who prefer visual programming or more advanced IDEs.
