IOT Gateway PCB design using Microchip SOM module

1. Current design is using RPI3 with connectivity to Ethernet, wifi, MBUS, LORA, WIfi and BT. 2. New design with microchip SOM module needs the same RPI3 form factor so it fits in our enclosure with the following interfaces Lora Module Ethernet Interface UART (3) SPI 1G Onboard flash Micro USB USB 5V Power input ( regulated 3.3 V power to Lora module) BLE Debug port for development 5 LED display for status Notes: 1)We may need to keep instance U11 for cryptoAuthentication. 2)We may need to keep QSPI device, U9, (flash memory) for second bootable memory. 3)Link to useful material: [login to view URL] 4. We have compiled our firmware on the eval board and it works fine.
