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.

We are the professional company and have years of expertise in electronics. We will work on all 3 devices and would make it. Let's discuss in chat box. Best Regards
I have already worked on lora and dlms protocol. so I can do your job and I know about morbus protocol . so I can do your job within a time limit with your satisfaction.
already worked on a similar project controlling the relays and sensors through cloud. my experience would be helpful in completing the work you want faster
