Ethernet
Ethernet is a popular networking technology for local area networks (LAN). Systems
communicating over Ethernet divide a stream of data into individual packets, known
as frames. Each frame contains source and destination addresses and error-checking
data so that damaged data can be detected and re-transmitted. This makes the
Ethernet protocol very popular for communication over longer distances or in noisy
environments.
Fusion for STM32 v8 features standard RJ-45 Ethernet connector (3) which enables
MCUs that support Ethernet communication to establish a connection with a personal
computer, network router, or other Ethernet network device. All four Ethernet lines (TX
P, TX N, RX P, and RX N), as well as the LED indicator lines (LED1, LED2+, LED2-) are
routed directly to the MCU card socket and cannot be accessed via PORT headers.
Additional GNDs
Fusion for STM32 v8 development board contains two exposed GND pins just above
the MCU card, which can be used to connect measurement or testing equipment.
These additional GND pins allow secure connection with the instrumentation probes,
avoiding loose cables or unreliable contacts that might compromise the accuracy of
the readings.
