Hi Andrey, I have one board - the sensor board (10324), which contains both the analog and FPGA components. This seems to be different than the configuration for the 363 sensor board (10342), which just had the analog components (there was a separate CCD control board 10347).
According to your website, the 323 camera consisted of: 1 - 4 of 10313 CPU/compressor boards (10313), one sensor board (10324), and one power supply board (10325). I have the sensor board, I can buy the processor board 10353 from you, and make the power supply board myself (maybe buying the bare PCB from you). If I order the 10353, can you install the 363 software on it? Will that software be able to operate the 10324 board without modification (I'm guessing the KAI-11000 and KAI-11002 are very similar)? Or, can I just use the image provided on SourceForge? ( https://sourceforge.net/projects/elphel/files/elphel353-8/8.2.16/) My other question is about the FPGA on the sensor board (Xilinx XC2S300E). Will it be stable after all these years? Do you have a copy of the image used to program it? I wondering just in case there is a problem with it. Thanks again for all the advice!
