The personal digital assistant (PDA) is seemingly a device of a bygone era, but the PocketMage PDA has been developed to help revive it for the modern day consumer. The device is constructed with a clamshell-style design that will open to reveal a 3.1-inch E Ink display that's accented by a tiny keyboard that's only large enough for typing with thumbs. The device is powered by the ESP32-S3 WROOM1 microprocessor and also has a 1.8-inch SPI OLED screen just above the keyboard for supplemental operating system support.
The PocketMage PDA isn't built for complex tasks, but is rather ideal for jotting down notes, journaling, managing a calendar and more. The device is expected to receive Google Calendar and Google Docs connectivity in the near-future for data syncing.
