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.
