1 year ago It is technically possible but I believe it would cause more confusion than it would solve problems:
- There are no plans to produce a version with PE426482
- If there were two different versions, the user needs to flash the correct firmware update (the hardware is unable to determine whether a PE426462 or PE426482 is populated). If the user flashes the wrong firmware by mistake, some functions would not work properly
If you yourself are building a version with the PE426482, I suggest you fork the repository and do the changes yourself for your special version of the device. You won't even have to set up the toolchain, just pushing the changes in your fork should get you a compiled firmware.

Hi Jankae, Judging by the layout of the printed circuit board, there will be physical changes only in the fact that in the case of the truth table Off, all switches will not be disabled, since V4 is connected to GND without reworking the board, and RFC needs to be switched to the RF1 output, which remains not connected anywhere. The changes are as follows - instead of RF4 and RF6 in pe426462, you now need to switch RF6 and RF8 in pe42482, respectively. In the truth tables in the new version, it will look like this:
Connection P1V1 | P1V2 | P1V3 | P2V1 | P2V2 | P2V3 | P3V1 | P3V2 | P3V3 | P4V1 | P4V2 | P4V3 Through_12 0 1 0 1 0 1 X X X X X X
Through_13 1 0 1 X X X 0 0 1 X X X
Through_14 0 0 1 X X X X X X 0 0 1
Through_23 X X X 0 1 0 0 1 0 X X X
Through_24 X X X 0 0 1 X X X 1 0 1
Through_34 X X X X X X 1 0 1 0 1 0
Instead of RF4 (011) now RF6 (101).
Connection | V1 | V2 | V3 |
Load 1 1 1 (instead of RF6 (101) now RF8 (111) ) Off 0 0 0 (instead of disabling all switches (110) now switching RFC to RF1 (000) ).
Best regards.
