design a serial multiplexer system that'll allow a single UART to communicate with 6 remote UART. Communication will happen in both directions. We're expecting you to select components, design the circuit assuming 5/3.5 V power-supply already present, design the pcb and write simple C based board support package. End application is NOT expected. The challenge in this project is minimizing cost.

I have a small closed network of PCBs, each with an ESP-32D as its controller. I am using an 18V power source that is connected to each with CAT-V on a custom (not ethernet pinout) format to feed the 18V and ground with two twisted pairs. There are two high voltage LM2596 buck converters that make 12V fo...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 ...
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.

I have a working PCB designed in Altium. Since we will do all future work in KiCAD, this project needs to be converted to KiCAD 6.0. The PCB has a MCU that receives data from two SPI radio modules and relays the data to USB, Ethernet and Bluetooth for further processing on a PC. The PCB also has two RGB LEDs, battery management, barometer, GPS module with active antenna detection, speaker and a few other features. The attached BOM contains almost all components. The PCB size is 63x87 mm. It's a conventional four-layer PCB with two power planes. The resulting KiCAD project will have identical schematics. The CAD footprints, layout and outline will also be identical. CAD routing is not necessary to do, since any future work will require the routing t...
