A314 board for the A1000's front memory expansion bay
This is the Amiga 1000 version of [the A314](https://github.com/niklasekstrom/a314), designed to fit in the front expansion bay of the iconic computer.
It is built using readily available components and has been designed with the DIY builder in mind (ie. no BGA chips, and reasonably large components with external leads)
It is a 1:1 replacement for the A1050 C= memory expansion, and will provide 256kB of chipRAM regardless if the RPiZ module is present.
The board has room for an optional RTC chip which can provide time and date to the RPiZ via an I2C bus. This bus has also been made available via solderpads and is accessible from both sides of the PCB. It can be useful if you'd like to add other peripherals, like RGB lights or an OLED display for instance.
For more information on how to bring this hardware to life, please check out Niklas repository at https://github.com/niklasekstrom/a314-1000-gateware

Questions
How big is the A314-1000 PCB?
It measures 163.4 × 59.5 mm and has 4 copper layers, 1.61 mm thick.
What parts does the A314-1000 use?
98 parts, built around the TLV62569PDRL, W25Q80DVSNIG, SN74CBTD3384CPWRE4 and IS61WV12816EDBLL-10TLI. 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 A314-1000 KiCad files?
From the Eriond/A314-1000-PCB repository on GitHub, at the commit this page was made from: the board is KiCAD/A314-1000.kicad_pcb and its schematic KiCAD/A314-1000.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the A314-1000 design in my own project?
Its repository states no licence, so its author keeps all rights: ask Eriond before reusing the design.
