This is a 8MB FastRam board for A1200 designed in 2019 by @edu_arana, coworked with Stephen Leary based on the TF328 project.
This project, as the same as the original, are released under the GNU GPLv2. If you build a modified version of the board you must supply the end user with all the sources (this can be a web link). Also you may create or base commercial PCBs from the work in this repository but you must make the sources for all derivative work available. The authors on this board must remain and stay legible on the current / new board. Removing the copyright notices its a breach of the GPL.
BTW, If you make a new board version, we will be glad if you send at least one pcb to each us. This is not a must :p
Dimensions : 59 x 100 mm
Layers : 4 layers

S. Leary a.k.a terriblefire has made an small modification to the current TF322 to disable the ide option, as the A1200 already have one. The firmware jed files are available on the firmware directory.
Xilinx ISE, 14.7 JTAG Adaptor
Stephen has made a new branch for the firmware used on this board. The current branch address is https://github.com/terriblefire/tf328/tree/edu1200_board
Thanks S.
Premade gerbers of the board are available on this repository too.
Note that the only ram chips used and compatible are the K4E151612C, this ram chips are 3v3 only. All the current design is adapter to 3V3. A new LDO regulator is used to get 3V3 vots.

There is a TF328 wiki that can be use to resolve any doubt about the compatibility of the current firmware.
