Need advice on HomeWizard controller replacement

I have my old Homewizard controller integrated in HA to control a substantial number of 433 devices I still use. It hasn’t been supported for donkey years and is breaking down. Long periods of not being accessible. No idea what’s happening.
If I understand correctly it could be best replaced by rflink (HA Rflink doc. That points to the Nodo webshop, I find many ‘rflink things’ there. Is THIS what I should buy (incl soldering)?

Thanks for your help.
