An open-source hardware and firmware project for a smart NFC card with an e-ink display, built on an STM32L051 MCU and ST25DV NFC chip. It includes PCB schematics, firmware, 3D-printable case files, a companion Android app, and a custom DAP-Link debugger design.
Use cases
- build a DIY smart NFC access card with an e-ink display
- clone multiple IC access cards into one physical card
- learn STM32 low-power firmware development
- 3D print a custom case for an e-ink NFC badge
- customize what an NFC card displays via a companion app
When to choose
- you want an open-source, hackable multi-card NFC badge with a display
- you need complete hardware files (schematics, gerbers, BOM) plus firmware in one project
- you want a hands-on embedded project combining NFC, e-ink, and STM32
When to avoid
- you need software-level ISO 14443 card emulation - this version only switches discrete UID chips
- you want a polished consumer product rather than a DIY build requiring soldering and flashing
- you need active development or support - the project has not been updated since early 2021
