I recently did a bit of research – searching this forum and browsing the Web (particularly useful is the “atlas of Arduino Ethernet shields”, at the Wayback machine link below, as the original site no longer exists) – to understand more about the development of the Ethernet shield.
I realise that the latest board is the Ethernet shield 2. I also know that Ethernet shield R3 is now available (only through third-part manufacturers) for the UNO & Mega R3 etc… However, I’m puzzled about Ethernet shield 06 in relation to shields 05 and R3.
I see that there are loads of shield 05 boards on the market from third-part manufacturers, whilst fewer R3 shields, but no shield 06 boards at all (I still have to find one).
My question is this: why are there no shield 06 boards available? I would have thought that the Shield 06 would have take precedence over Shield 05. In addition, considering the fact the UNO R3 is the latest UNO, is it also not strange that there are fewer R3 shields available, compared with the 05 board?
Perhaps I’m missing something? Any ideas?.. just looking for claification
