ESP32 & ETH Lan board with PWM output project change

Hello, i have a fully designed ESP32 with ETH Lan board ready: - ESP32 + ETH Lan + RS485 - MicroUSB form programming with Arduino IDE and loading "Arduino Code and Libraries" - 12 to 24 voltage powering range - 6 indipendent PWM channel with 12 to 24 voltage range (following input power voltage) - 1 input power supply from 12 to 24V for both power-on the board and all 6 pwm output - 5A minimum current per channel (30A total current) - 6 opto-isolated input What i would: - separate board power-on source and pwm output power source - reduce output from 6 to 4 - increase max current per channel - use separate power source for pwm outputs, one for each output, and each output power source can have a different input voltage (e.g.: first at 12V, second and third at 24V and fourth at 18V) So: - 1 input power source from 12 to 24V for power-on board (and as now can be powered by also microUSB during development) - 4 output power source from 12 to 24V, each output power source can have a separate voltage - 4 PWM output each one attached to correspondent power source and following correspondent voltage - No electrical connection, as far as possible, between "core" side (input, eth, esp32, rs485, ecc...) and output (output power sources and pwm outputs) - Increase max current per PWM channel from 5A to 7/8A or more (if possible) - Use of output power source connectors that can handle up to 30A (this will we usefull if i want to use only 1 power supply for all outputs and chain output power sources with wire) - If there is the possibility to attach to each PWM output a Voltage/Current "reader" so i can monitor power consumptions Keep untouched all others components: microUSB, eth, esp32, rs485 and 6 opto-isolated input (if there are free GPIO due to reduced number of output increase to 8 or more) So i need: - Proven ESP32 knowledge. - Project design check and validation of all requirements. - Edit current project files (Gerbers, Eagle, etc...) following previous requirements. - Help to create some proptotype with an online PCB & Assemply factory since i have not the known-how (send them file and so on....).
