Re: Is this project active?
Here you can find a BGA soldering masterclass wich I've done couple weeks ago
You have to use the latest version of Bootloader FW and MCU FW. You can have up to 3 different working FW in this device at the same time, preffered to use the latest version but it is not important.
The latest version of working FW may have important opernHPSDR protocol updates.
I am current owner and user Odyssey-2 and if it becomes necessary to correct a mistake or modify something, I will do it very quickly.
