|
|
|
## Overview
|
|
|
|
All hardware schematics and board files are designed using [KiCad](http://kicad-pcb.org) open-source CAD software.
|
|
|
|
> KiCad is free software. KiCad is made available under the [GNU General Public License (GPL) version 3](https://www.gnu.org/licenses/gpl-3.0.en.html) or greater.
|
|
|
|
All KiCad design files are available within the [HARDWARE](HARDWARE) directory within this repository.
|
|
You may download KiCad and open for reviewing or editing each of the PCB files.
|
|
The schematics are also available as PDF files for easier viewing and/or printing.
|
|
|
|
**NOTE**: Please use the latest KiCad nightly development build, as the latest stable build may not have all required features.

## Introduction to the hardware of TERES-I
|
|
|
|
TERES-I internal electronics consists of the folowing boards:
|
|
|
|
### Main board ([PCB1-A64-MAIN](A64-TERES/TERES-PCB1-A64-MAIN))
|
|
|
|
The main board (**PCB1-A64-MAIN**) is comprised of:
|
|
|
|
* A64 processor
|
|
* RAM and flash NAND memories
|
|
* Power management unit
|
|
* LCD converter
|
|
* Connectors to different interfaces
|
|
* and others
|
|
|
|
|
|
|
|
Alternative main board processors and memory configuration options will be available in the future.
|
|
These should be compatible with all other existing boards.
|
|
Subsequent revisions are expected to have increased processing speed and improved memory performance.
|
|
|
|
### Keyboard controller ([TERES-PCB5-KEYBOARD](A64-TERES/TERES-PCB5-KEYBOARD))
|
|
|
|
The **KEYBOARD controller** board (**TERES-PCB5-KEYBOARD**) is responsible for handling the keyboard and touch pad interfaces.
|
|
This keyboard controller board allows you to completely reprogram the keyboard mapping and response according to your own taste.
|
|
|
|
This board contains an AVR processor.
|
|
Sources, binaries and update procedures for AVR firmware are available at GitHub.
|
|
Keyboard/touch controller firmware may be updated live on the board itself.
|
|
It can also be programmed using an Arduino microcontroller.
|
|
Touch screen parameters can also be changed.
|
|
|
|
|
|
|
|
### I/O board ([TERES-PCB2-IO](A64-TERES/TERES-PCB2-IO))
|
|
|
|
The **IO** board (**TERES-PCB2-IO**) is comprised of:
|
|
|
|
- USB connector
|
|
- Headphone/debug connector
|
|
- SD card
|
|
- Speaker connector
|
|
- Microphone
|
|
|
|
|
|
|
|
### Power button ([TERES-PCB4-PWR-BTN](A64-TERES/TERES-PCB4-PWR-BTN))
|
|
|
|
The **PWR** button board (**TERES-PCB4-PWR-BTN**) handles the keys for powering on and off the laptop.
|
|
|
|
|
|
|
|
### Touch buttons ([TERES-PCB3-TOUCH-BTN](A64-TERES/TERES-PCB3-TOUCH-BTN))
|
|
|
|
The **TOUCH** buttons board (**TERES-PCB3-TOUCH-BTN**) contains two buttons for left and right mouse click emulation.
|
|
|
|
|
|
|
|
|
|
### Camera ([TERES-019-Camera](A64-TERES/TERES-019-Camera))
|
