I would like to have a ESP32 based board developed. It should be an efficient design in terms of reliability and power. Following are the requirements: 1. Develop complete working solution including hardware(Compact Circuit board) and software based on ESP32 2. Must support power source ranging between 10-32v 3. Should support at least 4 GPIOs upto 30v with isolation using optocoupler 4. External Antenna with SMA Connector 5. Two Serial Interface Connection other basic requirement will be shared later but before awarding the project. Please only show interest if you have already worked with ESP32, antenna, voltage dividers, optocouplers.

Hello, I have experience with ESP32 and all requirements that you've wrote. I use Altium Designer for PCB design and I've used Xtensa GCC with ESP SDK for ESP32 programming, but I can use Arduino IDE if you want to easily change software yourself. I work for a company that priduces devices for industry so I'm familiar with isolation, various supply voltages, serial and any type of communication, etc... I can also optimize board for cheaper and faster production and I can do some small scale serial production and testing. Thank you in advance. Best regards, Radojica Berak

Hi, We have already worked with ESP32, antenna, voltage dividers, optocouplers. To develop ESP32 Based Hardware and Software; There will be some hardware cost as well. Do have schematics? Otherwise we can design schematics as well. We got your requirements regarding Compact Circuit board & software development featured with Antenna with SMA Connector. Kindly spare 10 minutes for the interview process for better insights. Looking forward to hear from you soon! Regards, Harjit Singh

1,if u need esp32 separately (means not a development board i strongly recommending to use stm32 like ic's it have enough serial port and gpios..or you are looking with development board it's not need or if you have any controller in mind i am oke with that 2,it is not a big deal lm317 like regulators are available 3,i am familiar with optocoupler like pc817,me12e and also familiar with mosfet,triac,realys with optocoupler 4,i am oke with that 5,i think that choose depends on controller selection over all i am ready to do your circuit diagram with pcb(in kicad),i can send .grb files
