Identifying different Pano generations and revisions
The first generation (G1) Pano was based on the largest Xilinx Spartan-3E family chip and supports a single VGA monitor, 3 high speed (2.0) USB ports, 10BASE-T/100BASE-T Ethernet, audio input, and audio output.
The second generation (G2) supported two monitors, 4 high speed (2.0) USB ports, gigabit Ethernet, and audio output. The second generation does not have an audio input.
Revision A and B of the G2 devices were based on the Spartan-6 XC6SLX150-2 which is the largest chip in the family. The revision C G2 device is based on the smaller XC6SLX100-3 which is still quite large by hobbyist standards. The XC6SLX100 has fewer configurable logic blocks (CLBs) than the XC6SLX150, but the rest of the resources (on chip block RAMs, DSPs, etc) are the same. It is interesting that the Rev C uses a higher speed grade than the Rev B.
As far as is known both revisions are identical other that size of the FPGA and SPI chips. Any design that fits in the Rev C should also work on earlier revisions. Of course the bit stream must be generated for the correct chip.
The Rev A G2 has a significantly different PCB layout than the Rev B and C. The compatibility of the Rev A with the Rev B and C is currently unknown. If anyone has done any testing on a Rev A please drop by the Gitter chat room and let us know your findings.
The device revision should be printed on a stick on label with the MAC address.
Steve Gagnon found what is apparently an early prototype Rev A on ebay.
This is the most desirable version of the G2 since it has been used successfully by numerous people and has the largest FPGA and SPI flash chips. There are several projects support it.
The device revision should be printed on a stick on label with the MAC address.
The device revision should be printed on a stick on label next to the MAC address.
This is a very rare model of the Pano that apparently existed between the first and second generation devices. The generation labels were assigned by the hacker community not Pano and we didn't know much about these devices when the names were picked. Hence this device is now generation 1.5!
The model is very similar to the G2 device, but it only support a single DVI monitor.
This is an 22 in LCD monitor with a built in Pano device simular to the G2. See Zeljko Stevanovic's Github repo for pictures of the controller.
