Handheld Linux Device

This is a small, handheld Linux device designed for low cost and manufacturability. Of note, this device does not use lithium batteries, but rechargable NiMH AAA cells, as importing lithium cells is difficult; also, on a per-cell basis, NiMH are cheaper (with about 75% the capacity of Li cells).

Features

• Allwinner F1C200s SoC
  • ARM9 core with 64MB of MB SDRAM, running at ~500MHz.
  • This is in an easily-assebled QFP88 package with minimal support components.
  • 64MB Flash, microSD card slot

• 320x240 SPI LCD, based on ILI9432 controller

• A silicone keyboard, a lot like this other thing I built

• Injection molded clamshell case
  • May be produced in many colors, like red, blue, green, white, black, possibly even pink
• Rechargable NiMH battery
  • Because I’m not shipping lithium.

What it does

First off, it plays Doom, because it has to.

USB-C employs USB gadget protocol, allowing this device to become anything. SAO headers give serial, I2C, GPIO expansion, and reasonably stable software allows nearly infinite expandablity. It’s a Swiss Army Device, something that’s sufficient for nearly any job, but is safe at home in your pocket.
