M5Stack PaperDIY: A $25 ESP32-S3 E-Paper Kit You Assemble

M5Stack has a new e-paper board that doubles as a lesson in hardware. The PaperDIY Assembly Kit combines a 4.7-inch e-paper display with an ESP32-S3 module, a small battery and an acrylic pressure plate. It costs $25 on M5Stack's store, and you put it together yourself. LinuxGizmos reported the kit on October 16, and the shop listing shows it in stock.

• Price: $25 for the kit (SKU K159), listed with 10+ units in stock
• Brains: ESP32-S3-WROOM-1-N16R8 with a dual-core 240MHz LX7, 16MB flash and 8MB octal PSRAM
• Display: 4.7-inch ED047TC1 e-paper, 960 x 540, 16 grey levels
• Size: 115.3 x 62.5 x 5.5 mm and just 26.4 g

What's Inside the PaperDIY Kit?

The box holds the e-paper panel, the main control board, a 140mAh lithium battery and an acrylic plate that holds the screen in place. M5Stack is clear that assembly is up to you: there is no pre-installed 3D-printed enclosure, so you can design your own case or leave the electronics on show.

The control board is well specified for an e-paper project:

• Power: an M5PM1 power-management chip, USB-C 5V input, a 5V pad and an SH1.0 battery connector
• Storage and expansion: a microSD slot and two 12-pin 0.5mm FPC connectors for add-ons
• Controls: a multi-function power button (on, off, reset and boot) plus two user buttons
• Wireless: 2.4GHz Wi-Fi from the ESP32-S3

M5Stack lists active draw at about 41mA at 4.2V, peaking around 161mA during updates. E-paper uses almost no power while showing a static image. The modest 140mAh cell is therefore better suited to dashboards that refresh occasionally than to constant redraws.

Why Build Your Own E-Paper Display?

Most e-paper dev boards arrive sealed and finished. PaperDIY turns assembly into part of the project, which makes it a natural fit for classrooms, workshops and anyone who wants to understand how a display stack fits together. Once built, it becomes the base for classic ESP32-S3 e-paper projects:

• A weather and calendar dashboard that refreshes every few minutes over Wi-Fi
• A Home Assistant status panel showing sensors and energy use
• A minimalist e-reader or note viewer loading files from microSD
• A desk badge or room sign that keeps its image with the power off

Sixteen grey levels give smooth shading for icons and photos, and 960 x 540 is sharp enough for small text at 4.7 inches. M5Stack's product page links its usual tools, including UiFlow, Arduino and ESP-IDF. LinuxGizmos adds that Arduino is supported through the M5Unified and M5GFX libraries, and that M5Stack supplies a browser-based flashing tool and ESP-IDF factory firmware source.

How Does It Compare to Other M5Stack E-Paper Boards?

PaperDIY sits at the budget end of M5Stack's e-paper range. The M5Stack Paper Mono costs $65 but adds LoRa and NFC for off-grid messaging. Boards like the MaTouch ESP32-S3 E Ink board build in microphones for voice projects. At $25, PaperDIY trades those extras for the lowest price and the most hands-on build. LinuxGizmos also reports a $29.90 Complete Kit option that adds factory assembly and a case for buyers who would rather skip the screwdriver.
