# Solar-Powered Handheld Devices The Orion PDA Avoids Internet Connectivity by Design By Amy Duong | Published 2026-05-20 | Art & Design Source: Trend Hunter, https://www.trendhunter.com/trends/orion-pda References: [orionpda.org](https://orionpda.org/)  The Orion PDA is a [compact clamshell handheld computer](https://www.trendhunter.com/trends/mecha-comet) designed around offline use and low-power operation. It features a 3.16-inch monochrome Sharp Memory LCD with a resolution of 536×336 pixels, chosen for high visibility in direct sunlight and minimal energy consumption. The device includes a [full QWERTY keyboard](https://www.trendhunter.com/trends/lenovo-800-selfcharging-bluetooth-keyboard) for physical text input and runs a custom lightweight operating system focused on basic productivity tasks such as note-taking, music playback, and voice recording. The hardware is built around an STM32U575 microcontroller and includes microSD storage, USB-C for charging and data transfer, and a headphone jack. A [solar panel integrated into the lid](https://www.trendhunter.com/trends/portable-solar-tracker) supplements battery life, allowing extended use with exposure to light. Connectivity is intentionally limited, with no built-in internet access.
