README
README.mdTea Cup Tinker Board

The Tea Cup is a Tinker Board built on the Ingenic T31 MIPS CPU, which is specialised for Video & Audio Applications, and has highly integrated support for multiple interfaces, LCD's, SD Card, Ethernet and more.
Designed with the community in mind, the Tea Cup is going to be ideal for Kids, Tweens and Teens, and adults alike, to tinker with hardware and software inside of an interface designed with ease-of-use and simplicity, but never locking the user down to a limited API or enviroment.
This project is currently in alpha, with a small team working on it, you can join our commuinty Discord Server

Tools We Use
All of the work we are doing on Tea Cup, and any future projects are strictly open-source only whenever possible, This means we do not distrubiute any CAD, Code, Docs, or any other files in any format that is not an open-source, Free or FOSS Package, this is to ensure anyone can join development, and use our work in their own endevours.
Having this in mind, the tools we are using in this project are:
- FreeCAD
- KiCad
- binwalk
- Ghidra
- GIMP
Currently Working on:
- Getting an up-to-date SDK from ingenic
- Compiling uboot and attempting to create our own kernel with outdated SDK
- PCB Design for REV-A
- Testing differences between T31 Series and other Ingenic CPUs
- Finding a reliable and cheap method to get ICs from existing products
- Getting source for bulk order of T31's
Have finished:
- REV-A Roadmap
- Compiled and ran code on the host device
- Reverse engineering of the "$1 webcam" PCB, with full Serial comms
- binwalk'd "$1 webcam" Firmware and working on Reverse Engineering
- Discord Server with management and co-ordination systems
Long Term TODO

Thanks
To everyone who has worked with us on Tea Cup, we thank you sincerely. It has been, and will continue to be an honour working with you.
Thank you so much to the core-dev team for your continued work and effort with us on Tea Cup, without you this would have been impossible.
Thank you

Questions
How big is the Teacup PCB?
It measures 86.2 × 56.2 mm and has 4 copper layers, 1.58 mm thick.
What parts does the Teacup use?
95 parts, built around the T31ZX, W25Q32JVSSIQ, AZ1117IH-3.3TRG1 and NX2016SA-24MHZ-EXS00A-CS07553. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Teacup KiCad files?
From the HackerComputerCompany/teacup repository on GitHub, at the commit this page was made from: the board is PCB/Teacup/Teacup.kicad_pcb and its schematic PCB/Teacup/Teacup.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Teacup design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
