Yeah, that is the list I would worry about, it is important the core function to work as expected...

Actually if I go by this route, than probably I would not replicate it fully, important the source code is available and then perhaps I may simplify it a bit... I like the idea behind LCR2 of using ICL7135, while from 2Mhz Elector I like the use of DDS... all in all to use as many components which are available in my drawer...  However I really like github/jankae LCR and perhaps will pull the trigger for it...

Not derailing the thread

For the elektor, you wont get the source code, just the compiled code to put in the mcu ...  it would be too easy to copy    china "cough"  loll

the elektor lcr meter from 2013 has the sources available here :
