The PocketMage PDA is an open-source handheld productivity device developed by Ashton F. with a clamshell design, dual displays, and a physical QWERTY keyboard. The device combines a 3.1-inch E Ink display with a 1.8-inch OLED screen to provide comfortable reading alongside responsive typing feedback. An ESP32-S3 microcontroller runs PocketMageOS on FreeRTOS, supporting offline productivity through built-in applications including a Markdown editor, journal, calendar, task manager, dictionary, and file manager. The compact housing measures 100 by 73 by 21.7 millimeters, making it suitable for portable daily use.
A 1,200 mAh battery delivers up to seven days of operation between charges. The operating system supports community-developed software through the Bazaar app repository, where users can install tools such as an e-book reader, calculator, and text-based web browser. Expansion pins expose I2C, SPI, UART, and GPIO interfaces for hardware accessories.
