Below are links to the current firmware versions for the DPr, DPr/E01 and DPr-A digital transmitters.
These are zip files, after downloading extract them into a temporary folder. Each contains 3 files, one for the microcontroller, one for the FPGA and one bootloader file. Follow the instructions in the DPr Instruction Manual to update firmware. If you encounter problems while updating the firmware please contact the factory for assistance.
How do I decide which firmware version is right for my transmitter?
The FPGA firmware version is displayed in the "About" page in the "Settings" menu.
