The ZecTrix Note 4 is a 4.2-inch e-paper smart display designed to present reminders, notes, and schedules without the distractions of a smartphone. Users can press a physical button and speak a task, which the built-in AI voice assistant transcribes and adds to the display. The low-power e-paper screen also supports handwritten notes, clocks, weather updates, focus timers, images, and customizable templates while retaining content without continuous power consumption.
Powered by an ESP32-S3 processor with 8MB PSRAM, 16MB flash memory, Wi-Fi, Bluetooth 5.0, NFC, a microphone, speaker, and a 2,000mAh battery, the device attaches magnetically to metal surfaces for flexible placement. ZecTrix also offers the Note 4C, a four-color E Ink version intended for developers, featuring the same hardware but an open software platform for custom projects. Multiple enclosure options, including open-source 3D-printable designs, expand the system's customization potential.
