1. The architecture is decided as follows
GW 2.0(Controller PCB + 4G PCB + Connector PCB) + IOPCB (USB Connector, 1-AI, 1-DI) + LED PCB
2. New components/interfaces
AI is based on ADS1115 (I2C)
DI is based on optocoupler(sinking) & GPIO
USB is TypeA (3.0, 9-pin)
3. The enclosure needs modification - remove SPI LAN cutout, use USB cutout, extend connector cutout
Documentation in ISO format to be done
