This update really only needed the SPI nSS connected to the Raspberry Pi's CE10 pin. The change of the transceiver was not really important, other than showing a different one that should work (if it works it cost less, but that is likely bait). Removed stuff (terminations, manager ADC6, and ADC7) for simplification. Routed I2C1 to the R-Pi SMBus so only populate this board with a ATmega328pb which was proven with RPUadpt^6 (a 328p will damage the R-Pi SMBus pins).

What do you think about the slogan? I think "Intelligence at the network edge" was Intel's but my interest is more in having the tool-chain at the edge. It means I can bootload directly (not through an adversary) and no network stack so simpler microcontrollers are viable.
