Circuit Design Jobs

Hi, I'm looking for an PCB expert that can design the circuit, the gerber files for pcb printing and create a list of needed component to assembly the pcb. We currently have a prototype device based on the ESP32 and want to build a PCB. The PCB must be sized to fit the box/case. The device has ESP32, SIM800, PCF8563, 1 x 5V Relay, INA226, MAX13487, SD card holder, 2x PC817 and DC/DC IC's... The device does not contain many components. We adhere to a precise design, consistent with the documentation of the individual components and modules. Further details will be specified in the chat. thanks

We have a processor board [using a TI RM57] that needs a secondary board to interface with, the design work is related to the secondary board. We have begun the schematic design based on previous working boards, but are looking at options to out source this and other design work. We can provide a schematic which will need some finalisation and verification. The finished design should include finalised schematic, finalised pcb layout, finalised production files.

I am looking to develop a circuit using a Bluetooth Low Energy (nRF52832) temperature sensor with a battery included. The sensor must be wireless and the battery is a required component. This project will require a high level of technical expertise, as I'm looking to create a sophisticated device that can track temperatures in real time. My goal is to create a reliable circuit using the most cutting-edge technology available, so I need someone with a deep understanding of BLE and other wireless technologies. If you're the right person for this job, I would be beyond thrilled to work with you.

Hello there, I am looking for a average Freelancer to help me out with a school project involving OrCad PCB design. It will be a simple two layout. This board is needed not to be perfect as per schematic but just for a school project. If you possess the necessary skills and experience for this type of work, I look forward to your bids and to working with you. Thank you for your time and consideration!

Good Morning, I'm looking for an electronical expert that can design the circuit, the gerber files for pcb printing and create a list of needed component to assembly the pcb. The circuit will be a simple circuit with a nodeMCU esp8266 module, with one single relay with octocoupler, Sim900 Gsm module for remote connection, data source to read if the relay is currently open or closed and if the device is connected or not, autonomus 12 v alimentation jack, led for pcb status(is on or off), led for connection status, led for relay status. The delivery of this project includes: 1* Full circuit design, Gerber files needed for printing, 1*detailed list with all the components needed to assembly the PCB once printed. The contest will be awrded once the circuit has been tested with ma...

I am looking to hire a freelancer to control output according to water level and temperature via nextion display. I need this project to be completed ASAP. Although I did not specify what type of output or sensors are needed, I expect the freelancer to be knowledgeable and experienced in creating projects such as these. I am looking for someone who is available and eager to take on this project, and can provide me with a satisfactory end result.

Hello! I am looking for help with my PCB designs review. I need an expert in PCB layout design to conduct an electrical review of my designs. I have documents available to provide, making this review easier and faster. I am searching for someone with the right expertise - someone who can evaluate my PCB layout which has USB port impedance matching etc..and need to make changes to the design. The boards are completed and only the review and rectification work is freelancer should know about ESD protection, Diode (schotkey and TVS) and impedance matching for USB port. All files are designed in EasyEda.

I have a massage headspa bed imported from China and it’s not working properly. I have had both an electrician and plumber look at it and they suggested an electrical engineer to see if they can get it working. Many thanks

I am looking for someone with extensive knowledge in electrical designing and ETAP (or similar) software related hand calculations. Specifically, I need someone who is well-versed in AC Circuits, has experience using ETAP or similar software and can provide calculations based on the designs. Need to understand how the work could be done by hand calculations and compared using ETAP.

I would like to hire a freelancer to design a cooling system that dissipates heat from rechargeable batteries. MOFs, a metal foam material that absorbs water, wrap around lithium-ion batteries for electric vehicles. As the battery heats up, the water in the MOFs evaporates, taking the heat away and dissipating heat. The whole process is simulated by simulation software, and drawing a conclusion. Heat dissipation under different discharge power (3c and 5c) needs to be simulated. The Freelancer will be responsible for designing and implementing this system, using the evaporation principle to dissipate heat from the rechargeable battery. The Freelancer should have experience in designing cooling systems, and should be experienced with utilizing the evaporation principle. The relevant papers a...
