🛠 Getting started with M5Stack PaperDIY

Objectives

This tutorial aims to assemble the PaperDIY kit, establish reliable serial communication, and flash the base firmware to validate the ED047TC1 e-paper display and ESP32-S3-WROOM-1 module.

Materials needed

• M5Stack PaperDIY Kit (components to solder or clip)
• USB-C data cable
• PC with Arduino IDE or PlatformIO
• Soldering iron and solder (if not pre-soldered)

Steps

1. Mechanical Assembly: Insert the ESP32-S3-WROOM-1 module into its socket. Carefully connect the 4.7-inch e-paper display ribbon, respecting the connector orientation. Attach the 140 mAh battery to the dedicated JST connector, respecting polarity.

1. Dependency Installation: Open Arduino IDE. Go to *Boards Manager* and add the M5Stack board manager URL. Install the "M5Stack-ESP32-S3" board.

1. Port Configuration: Connect PaperDIY via USB-C. In *Ports*, select the corresponding COM or tty port. Ensure the physical button is accessible.

1. Firmware Flash: Open the "HelloWorld" example from the M5Unified library. Select the "Paper" model. Click *Upload*. If flashing fails, hold the BOOT button while connecting USB to enter download mode.

1. Visual Test: After flashing, the screen should display text or a logo. The e-paper uses an 8-bit parallel interface; ensure no wires are desoldered if the display remains white.

Verification

Open the Serial Monitor at 115200 bauds. You should see initialization messages for the ESP32-S3 SoC (dual-core LX7) and 8 MB Octal PSRAM. WiFi 4 and Bluetooth 5.0 LE should initialize without errors. If the screen does not light up, check the ribbon soldering and battery voltage via the M5PM1 chip.
