I have the ebus adapter with version 3.0, which is not properly working at my vaillant system. I assume it is because the bus does not give enough power. Is it possible to attach the v3.0 to a seperate power supply? I can not find any documentation on the version3.0 thank you

Hi, on v3, TP2 is the same but:

there is no TP3 but you can use BUS GND for GND
there is no JP1 so you need to use 24V power supply or remove D4 for use with lower voltage supply

Thank you! is it possible to supply the board with 3.3V over the programming interface? By the way I am on the inform list for the latest version...

It MAY work but I would not recommend it.
