I am looking to have a simple clean Fritzing PCB layout and build for a very simple Arduino based chess clock. I need a small quantity (10) of these code is already written.
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 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

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...

...and read the value of a 4 byte counter on an external clock (25 to 50 MHz). The 6 x 2 bytes values of the 6 analog signals, plus the 4 bytes of the counter and 1-2 bytes for with the board identifier will be streamed via Gigabit ethernet as UDP packets (about 1000 x 20-bytes events in every packet). The board should sustain a trigger rate of the order of 1 Million per second or higher. This project should be implemented on a MCU, as it is to replace a similar board based on FPGAs. The MCU will read the external ADC (6 independent ADCS able of at least 1 Ms/s each, at 12 bits). A 32 bits MCU based on multi-core ARM at 1 GHz or more would be required to handle the trigger rate. At a first stage, the functional analysis and simulation of the board should be presented and approv...
