Hi Graeme, yes, the supply chain for electronics right now is a complete mess! If you check the latest BOM, it is possible to use the blue INA219 boards, which are cheaper and easier to find than the purple one. Or are you having difficulty finding other components?
I'm building the larger multi board Sim which to be honest is a bit expensive and a pain to get the parts for.
