U16 DS9503P 1-Wire ESD protection diode 9. U2 - USB 7 Ports HUB chipset J1 (JP3) USB HUB upper port signal input from Rs-Pi 10. J13 Mini USB 5V input for USB Hub, you don't need plug 5V , the USB Hub already use 5V from Raspberry Pi (P1 pin2), if your USB device need more power, then you can plug-in 5V in this port. 11. J11 for RS-Pi V2 GPIO connector (got 4 more GPIO pin) |
