ESP32 & ETH Lan board with PWM output project change


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)


- 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....).

Beceriler: Arduino, Mikrodenetleyici, PCB Düzen, Internet of Things (IoT), PCB Design and Layout
