There are two high voltage LM2596 buck c...addition of a transceiver chip: SN65HVD). The CANbus is working fine throughout. However, when I power the network and connect the nodes, I am frying the ESP-32s. I verified that the 5V pin on the ESP-32 is indeed only getting 5V so it is not being overdriven there. I am trying to figure out why the ESP-32s are failing (they get very hot and eventually (a few minutes) die miserably). I've attached the PCB schematic. I'd appreciate any help with design but mostly need to figure out why the ESP-32s...
I am a junior electronic and mechanical engineer. I am making a product for agriculture use. For this state, i need someone to review the pcb design before manufacture and give me the comments. Later, we will ask for the whole design of other boards, but for the moment is just an advisory. There are 2 boards of 4 layers and i am using esp32wrover. My idea is pay by the hour. I dont really know how much time it will need.

Hi, I have PCB and schematics files generated from eagle. When I import them in easyeda it gives error. Most probably they are generated using older version of eagle. I don't have latest version of eagle so I want anyone having latest(or not too old) version of eagle which can upgrade old schematics and pcb files to latest version. It's a small task, you just need to import files in your eagle and save them Leg me know if anyone can do it Thanks
