Pcb design jobs

Hello, I have a pcb with ESP32 S3 that has bluetooth capabilities. The bluetooth is acting as a server and receives connections from an iOS app and from another ESP32 S3 configured as client. Code is written in Arduino IDE. My problem is, I do not seem to have BLE 5.0 range results, the range is similar to BLE 4.0, which is around 5-10 meters. I have been doing some digging and it seems ESP32 S3 with BLE 5 has 3 types of PHYs (physical layers): 1M, 2M and Coded PHY. As far as I read, default is 1M? (which is BLE 4 range basically). My goal is to adapt my code in order to support 2M PHY (100m range or so) or even Coded PHY (500-1000m), so the BLE connection can work at more than 5-10 meters. Thank you! Marius

Hi Valery N. I want to start the PCB project. Please guide me trough step by step.

Please have a read through the attached specification. I'm very happy to answer any queries about it. My background is mechanical engineering with very little electronics experience, so the spec is based on my perceived expectation that it is technically feasible. I am receptive to feedback where you think issues may arise. I'm particularly interested in anyone who can introduce me to a PCB manufacturer (China based ideally) to accelerate the process. For clarity, we can flesh out the prototype cost in addition to the cost of the programming etc. kind regards, Alex

I require a PCB that can shorten the duration of a DC signal by 30%. It would need to be a 6 layer PCB capable of dealing with 6 separate signals simultaneously. It would be handy but not essential if it could be reprogrammed to shorten the signal by different amounts. It would be helpful but not essential if it could keep a tally of how much it shortened the signal as an aggregate as it goes and send that information to an ap.

I require a 40vdc - 1000VDC to 12v UPS Isolated Power supply. Input 40-1000vdc (dual input / this means that both inputs go to the same point on the PCB but all that is additional is blocking diodes to make sure that power cannot flow though them in reverse between them) Dual Output: * Output 1 24vdc@10a continuous * Output 2 12vdc@5a continuous Backup battery 24v (should be charge by the power supply) 8 cell LiFePO4. Should have a 8 cell BMS chip to monitor and balance the cells. Should track the state of charge of the "Battery" Configurable charge current to charge the backup battery Max should be 15a.

Hi, We looking for some with a lot of dedication and a spare time to help us to setup and image detection system on an RPI, and also program it for other tasks, as well other systems that we are building. And If you are a skilled electronic hardware designer engineer, it is a plus. This project will last for 12+ month, in smaller 1–4-week projects now and then. We are on a tight budget, so a low timely hour fee is a must as it may be many hours over time. Every person involved in finishing our project, will for their long-time loyalty, be given stock option in our company, vastly more valued than your initial contract value.

Need to measure power and phase difference between two electromagnetic waves at ISM band of 2.45 GHz and bandwidth less than 100 MHz using MMIC's like AD8302 and power measurement with AD8364 in a 3-4 layer PCB, for monitoring load impedance and signal dissipation in a waveguide. DC o RMS processed signals must be sampled and digitized to be transmitted over an I2C bus with an ADC like Seeed Studio XIAO SAMD21

Hi Md Abu Sakib M., Hello again long time. You designed the hydroponic garden pcb for us sometime ago. We have sent the files again to pcbway for prototype and now they have more question. Are you available to help again? I can send you the files with their questions if you accept. Also when we do finally get the boards done would you also do the coding for us or make a reference to someone? Hope all is well and look forward to your response and finishing this job. Thanks again. Bill

We are transforming our small company in Asia from being a traditional German machinery company into a young and dynamic setup. We are delivering machines into PCB manufacturing industry. To remain competitive, we need to change our image. Our webpage is still old, the PPT Template we use are outdated and not functional. Look at , that is our current (ugly) webpage. I need a PPT Template that includes the core elements like circuit diagrams and the company logo, watermark backgrounds. i need several different slides to make the PPT more appealing. It should be rather bright but still using the corporate colors red, white, dark grey and light grey. thanks Elmar

...moisture sensor. It is based on the interdigital capacitor and will be manufactured on a PCB. I will need the formula(s), with a brief explanation, in order to calculate the total capacitance of the PCB probe (when it is on the air and when it submerged on the water). My aim is to use these parameters (along with the others parameters from the electronic circuit) with an optimization algorithm and find the optimal capacitor design. And then compare the theoretical values with the actual ones. Therefore, all parameters should be included, such as: - Number of fingers (N) - Length of finger (L) - Width of finger (W) - Gap between fingers (G) - Substrate dielectric (of FR4) - Height of substrate - Height of PCB trace - (and any other that I am not aware of)...
