[En-Nut-Discussion] EtherNut r2.1 with a SIPX483 speeds greaterthat 250kbps

As far as I can say, there are three main criteria for
RS485 drivers:

1. Speed vs. slew rate
2. Number of nodes, that can be driven
3. ESD protection

Rudy Van Raemdonck suggested to replace the Sipex by
a TI type capable of driving 128 nodes, but they seem
to be difficult to purchase. So we still mount Sipex
SP483ECN. Another interesting manufacturer is
