Design a Wireless IOT I/O Modbus Product

Design two 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 ESP-32, 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

The freelancer must have some experience with IOT already.
The PCB will fit in a enclosure provide by me, with drawing and physically.

Please include the sentence #I work with IOT#
