Orion is a modern PDA build from scratch, a personal digital assistant inspired by the Sharp Zaurus and the early 2000s devices.
Highlights:
• Sharp Memory LCD (3.16", 1-bit, sunlight-readable, ultra-low power)
• STM32U575 @ 160 MHz
• WM8904 audio DAC + digital MEMS microphone via ADF + DMA
• Custom rubber-dome keyboard
• SD card, USB-C, expansion port (WiFi module/radio etc..)
• Solar charging
Music playback, voice recording, notes, and video playback — all running on a device I designed from the ground up.
