E-Ink Digital Art Frame Kit with ESP32
E-Ink Digital Art Frame Kit with ESP32 – Battery-Powered E-Paper Art Display
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Turn a crisp 4.2-inch e-ink screen into a wall-mounted art frame that cycles through your favorite bitmap images on a schedule — all powered by a single LiPo battery for weeks. Perfect for showcasing minimalist art, black-and-white photography, or memorable quotes in a completely silent, zero-glare environment. This kit eliminates the guesswork of sourcing and integrating low-power components, leaving you with a polished piece of functional art.
What You'll Build
A self-contained digital art frame with a high-contrast, sunlight-readable e-paper display. You’ll configure it to read .bmp files from a microSD card and change the image at preset times using a real-time clock. Deep sleep between updates means the frame can hang anywhere without a power cord, ideal for gallery walls, living rooms, or even a standalone exhibition piece.
What You'll Learn
- Interfacing SPI e-paper displays with the ESP32 for fast, flicker-free refreshes
- Reading and rendering bitmap images directly from a microSD card over SPI
- Implementing ultra‑low‑power strategies: deep sleep, ULP co‑processor wake‑up, and RTC alarm scheduling
- Designing a complete battery‑powered embedded system with charge management and regulated supply rails

Who This Kit Is For
This kit is designed for experienced makers, B.Tech ECE/EEE students working on embedded capstone projects, and professionals prototyping low‑power IoT devices. Smart India Hackathon participants will find it a solid base for e‑paper and battery‑operated art installations. If you’re an artist or designer wanting to embed digital artwork into a physical frame you fully control, this kit provides the perfect canvas.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Scan the QR code included in the box to access an AI companion that walks you through every connection, code snippet, and power optimisation step. WhatsApp support is also available if you ever need a human perspective.
Can I display JPEG or PNG images directly?
The firmware is optimised for 1‑bit and 4‑bit grayscale bitmap (.bmp) files. We provide conversion scripts and free tool recommendations so you can easily turn your artwork into the right format before copying it to the SD card.
How long will the battery last?
With scheduled image changes every few hours and the ESP32 in deep sleep the rest of the time, the 2000mAh LiPo typically lasts 3‑6 weeks. The RTC and power management circuit are tuned to keep quiescent current below 10 µA.
Can I update images without opening the frame?
The microSD card is accessed via a small slot in the enclosure, so swapping images takes seconds. For advanced users, the ESP32’s WiFi can be enabled to fetch new bitmaps over the air and store them on the card automatically.
4.2in e-ink display shows bitmap art images fetched from SD card on schedule. Ultra-low power from LiPo.
