Add pinouts to ICs
*PA9(TX) = USB D+
*PA10(RX) = USB D-
====Si4063 (SPI_1)====
'''NFC/RFID 4k EEPROM'''
*PC13 = RF WIP/Busy(Pin 7)*PB6 = SCL(Pin 6)*PB7 (''needs confirmed, signal routes under STM)'' = SDA(Pin 5)
'''STG719 (DPST) - U2'''
*PC11 = IN(Pin 1)
'''STG719 (DPST) - U3'''
*PD2 = IN(Pin 1)
'''STG719 (DPST) - U4'''
*PB5 = IN(Pin 1)
'''STG719 (DPST) - U5'''
*PB4= IN(Pin 1)
'''DG636 (Dual DPST) - U6'''
*VDD = ENABLE (always HIGH) (Pin 2)*PA10 = A0(Pin 1)*''UnknownPin#1'' (routes under STM) = A1(Pin 14)
