ラズパイのモデルを調べる
cat /proc/cpuinfo
raspi4 Bの場合。
Hardware : BCM2835 Revision : d03114 Serial : 1000000066323307 Model : Raspberry Pi 4 Model B Rev 1.4
我が家においてたRaspi３はB+じゃなくBだった件。
ずっとB+だと思ってた。
cat /proc/cpuinfo Hardware : BCM2835 Revision : a32082 Serial : 0000000098ace381 Model : Raspberry Pi 3 Model B Rev 1.2
あー。
rPi ３は、100Mbps
USBで、100Mbpsなのでそれを使って、識別もできる。
