Design a LoraWan IOT I/O Modbus Product

Design 3 products as I will provide the enclosure and the freelancer must provide the PCB complete design to fit within it and also firmware with a little webserver.

The product is an I/O wireless based on LoraWan module, with external antenna communicating in Modbus.

1) It will have two relay outputs and two optoinputs, as well as a watchdog timer circuit communicating in a TCP Modbus Network

2) It will have 4 analog input and 1 analog output as well as a watchdog timer circuit communicating in a TCP Modbus Network

3) It's a RS-232/422/485 LoraWan Converter to communicate with those products above.

You have to design 3 small PCBs, about 80 x 60mm. Just to clarify!
The case file drawing is attached. You will also get a physical unit.
