# numini
A small CPU and a computer built around it.
## Overview
Currently, the planned hardware is based around an [iCEBreaker] and an [Inkplate 6].
The [original Inkplate 6 case]'s top is used (since the Inkplate came glued to it), but the bottom is replaced by a 3D-printed custom case that leaves room for the remainder of the components and ports on the bottom.
The Inkplate provides power via a lithium battery, and access to its display, its microSD card, and its Wi-Fi and Bluetooth connectivity.
The iCEBreaker is connected to the Inkplate over both I²C and UART.
The iCEBreaker is augmented with a [quad HyperRAM PMOD] module, which it uses for main memory.

[quad HyperRAM PMOD]: https://1bitsquared.com/products/pmod-hyperram
The different components are in the following subdirectories:
- `case/` contains the [OpenSCAD] code for the case design.
- `fpga/` contains the [Bluespec] code that runs on the iCEBreaker.
- `inkplate/` contains the code that runs on the Inkplate.
- `simhost/` contains Rust code that implements simulated peripherals for bluesim.
