Looking for an experienced designer / electrical engineer to move further with our products. We currently have 4 projects that involve ESP32, FPGA and MPUs. We're hoping to find someone who will be able to work on our other projects after completion of the first one. This particular project involves a 4 single layer board design using ESP32, solar power management, super capacitors and SPI display. We're looking for someone who is able to complete the project based on the requirements and is able to provide consultation on the future designs.

This is a pcb modification project which was done about a year ago. A new external antenna needs to be added in this pcb , so modification requires according to the specification.

I need someone to create a design of a pcb that generates pulses that turn on and off a magnetron for my project. basically you have to use a voltage controlled oscillator which controls a vacuum valve and modulates the high voltage frequency of the must be controlled by a pic.

...has a small size and has a low number of components. The input of this supply would be derived from a 12V source. The control of the Power Supply is open for discussion. It can be based purely on software (digital communication between this PCB and the control PCB) or voltage-dependent feedback (ADC/OpAmp based on this PCB, with the control signal generated on the control PCB). The input 12V is biased at -40kV, and therefore this PCB will be floating at a potential of –40kV. Any mode of communication that is not affected by the fact that this PCB would be floating at –40kV can be implemented. Please discuss the approach to establishing communication after due literature review. Due to the current supply chain scenarios, componen...

The work consist in modifying an existing 3D model of a small enclosure (110x50mm) for electronics PCB. The enclosure is made of two parts: the base part and the caps that clips onto the base part. The electronics is located inside the enclosure. The 3D model was initially designed with Catia and later imported to AutoDesk Inventor for further modifications. Before starting the project, it will be decided if the existing 3D model have to be modified or if it is needed to do reverse design of the existing 3D model before modifications. The model and documentation of the modification will be provided later after discussion. Thank you

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
