Altera Quartus release 24.2 brings some surprising news. The installation includes DLL files with "blaster3" in the filename, so the USB Blaster III support is really in the distribution included. There has however been no public announcement yet. The real release of the UB3 is planned for Quartus version 24.3, so this is the time when it will be announced.
UB3 is based on FTDI's FT4232H chip. For onboard solutions, FT2232H can also be used. A single RGB LED is used for status. Integration schematics will be made public. No license or fee is required; anyone can use the onboard UB3 solution.
As of today USB-Programmer2 von Trenz Electronic uses UB3 compatible circuitry. For some reason Quartus 24.2 still does not recognize this programmer without Arrow DLL's, so we all need to wait 24.3 release.
