Pinout and connectivity of the M5Stack PaperColor module
The module is equipped with numerous hardware interfaces enabling integration with additional devices and sensors. The E Ink display communicates with the microcontroller via an SPI bus, while the SHT40 sensor, RX8130CE RTC, and M5PM1 power management system share an I2C bus. A Grove HY2.0-4P expansion port (Port A) is available, providing GPIO4 and GPIO5 lines along with a 5V power supply and ground. This allows for quick, solderless connection of compatible Grove and M5Stack modules . Additionally, the device features an IR transmitter , two programmable RGB LED indicators, three user buttons, and a microSD card slot connected via an SPI interface. The audio system uses an I2S bus for communication between the ESP32-S3, the ES8311 codec, and the ES7210 DAC, allowing for projects involving audio recording and playback.
M5Stack PaperColor offers an extensive set of interfaces that facilitate integration with additional sensors, modules and actuators.
A USB Type-C connector is used to upload software and communicate with a computer.
M5Stack PaperColor Programming
The M5Stack PaperColor supports several popular programming environments, making it suitable for both beginners and advanced users. The manufacturer provides full support for the Arduino IDE, PlatformIO, ESP-IDF, and the graphical UiFlow2 environment based on block-based programming.
