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:

4. We have compiled our firmware on the eval board and it works fine.
