I am looking for an experienced freelance engineer to create a Gerber file for a simple electronic product. The product should feature a PCB and a board size not exceeding 100mm x 100mm. It should also be designed with a high degree of accuracy, precision, and attention to detail. The engineer must have a thorough knowledge of the various board materials available, as well as the design techniques and practices needed to create a product that meets all requirements. I expect that the final product will have all holes perfectly aligned, traces perfectly soldered, and components securely mounted. Reliability and quality are of utmost importance to me, and I am confident that this is achievable with the right note of expertise.

OBJECTIVE: SETUP AN HTTP PAGE ACCESSIBLE ON LOCAL NETWORK AT A FIXED IP ADDRESS (FOR EXAMPLE ) WITH W5500 MODULE AND ANY STM32 NUCLEO BOARD. We need someone to write firmware for a basic webpage to control/monitor our PCB using the W5500. We need someone with lots of experience with STM32 and access to some nucleo/dev board. Ideally you would also have the W5500 module (or W5100) but it's not required. It should be a rather simple project if you have experience with using W5500 with STM32.

Dear sir or madam. I would need help with programming. I already have an arduino program for my design (pcb with atmega328 ic) - it is about temperature regulation and also I use 1.3inch lcd display with ST7789 board for showing data. The problem is that if the screen freezes, it doesn’t refresh automatically and stays freezed (I need to unplug and plug again the power). I would probably need separate program for the screen, which would recognize when the screen freezes and then refresh it. Or do you maybe know any other solution? I hope that someone could help me. Have a nice day! Gašper Vidmar

Create schematics and PCB layout based on the existing project design. The PCB should be designed in a way that it is easy to assemble and manufacture. Pick an appropriate microcontroller based on the requirements of the project. The microcontroller should have enough processing power and memory to handle all the required tasks. Consider factors such as cost, availability, and ease of programming when selecting a microcontroller. Add a gyroscope to the design. The gyroscope should be selected based on the required range, sensitivity, and accuracy. It should be compatible with the selected microcontroller and should be able to communicate data to it. Consider adding an accelerometer to the design, if required. The accelerometer should be selected based on the required r...

Need an electrical designer to help document power board scopes with schematics for fit outs, More details will be shared over a chat

However, instead of physically designing the board, the designer will create a digital representation of the PCB using specialized software. This digital file will contain all of the information necessary for the manufacturer to fabricate the physical board. During the design process, the designer must consider factors such as signal integrity, power distribution, thermal management, and manufacturability. These factors can have a significant impact on the performance and reliability of the final product. Once the digital PCB design is complete, the designer will generate manufacturing files that provide the necessary information for the manufacturer to produce the board. This includes information on the size and shape of the board, the location of components, and the routi...
