Amplifire schematics pcb jobs
We have tested the Analog Devices ADuM4160 USB port isolator IC and the ADuM5020 DC-DC converter (using the CN0419 evaluation board) and it works very well for our application. I would like to manufacture a small run of PCBs, assembled at the board house, based on the CN0419 eval board, with some small modifications; - The switch can be replaced by a small jumper, factory-default to full speed USB - The indicator LED is not required - The USB type A plug should be on a short shielded flylead We like that the eval board has good shielding, excellent performance, test points and fixing holes for an enclosure. Can you design a suitable board based on the CN0419 design, using the ADuM4160 and 5020 and current and available components, and produce the necessary files for manufacture?

Hi, I need a PCB design for a UK smart plug. Image below for the type of thing I'm looking for. It needs to be a UK plug that can plug into a UK plug and has a wifi and bluetooth module on it so that it can be turned on/off remotely (using both bluetooth and wifi for testing). It also needs to be able to monitor power usage for both how much power is being sent to the plug that's plugged into it, and also the power being used by the pcb (and the components that are on the PCB). During the design process, you 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. The final deliverable will include info...

To check beam angle and optimize design to meet our target. I need somebody to simulate and optimize lens shape of Interior lighting fixture to meet target beam angle. Design tool is LighTools, Tracepro or zemax,... whatever Fixture includes 1pcs 870mm PCB in length and 1pcs extrusion lens cover. Attached is target beam angle of the light. This is an urgent job and I need to finish it in 8 hours later.
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...

Hi there we have the dimensions of our PCB and components BOM list ready along with instructions. The list is very small and we just need to get the gerber files so that we can manufacture in china. Initially we will only attach the sensors on this board and later we will attach a Nordic chip that will control everything. After this job we will start a 2000 dlls job where we will add the Nordic and all other components. Lets talk asap and hopefully hire you today. We would love to get this manufactured ASAP

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...
This is a simple project as the work is already done.

I need to have a simple PCB Board manufacturered. The function of the board is to control a 6-12V pump when the pir sensor is activated. The pir sensor used is a SR501. The board should use an esp with wifi connection. Both the pump and the board is powered from the same source: 2 x 18650 batteries (so 7.4V) On the board there should be 4 connections: - Micro USB for the esp - Inlet power from the batteries - outlet power to the pump. - connection for the pir sensor The pcb board should be as small as possible. THIS IS VERY IMPORTANT
Looking to have this board remade with all its components. It’s very simple. Thank you
I'm looking for someone with expertise in MATLAB analysis for Controller schematics . In particular, I need help with it . I don't have any existing MATLAB code or data yet, so I'm looking for someone to help me develop it from scratch. The data is relatively small and simple in size and complexity, so I'm expecting this to be a straightforward assignment. I can give you the refernce document while discussing the project
I want to do a wifi button with a custom PCB using an ESP8266EX wifi chip.
The preliminar idea of the project is to buid a device based on a STM32, that controls a 4 inch LCD screen with RGB interface, with 2 to 4 serial data signals and 4 to 8 buttons. Design using easyEDA and prototypes made by jlcpcb. All this can be modified by designer advice. The work is design and test of the PCB. More details: - The work is to design PCB and schematic - The circuit has a 12V power source - The LCD is not deciced, but has to be high bright, problably RGB888, to be decided - The serial data bus is CAN - The LCD probably has a backlight power voltage of about 15v - I decided to use easyEDA because I know it, but also to be decided - I decided to use STM32 because it has support for CAN bus and RGB888, but again to be decided Regards
I have all of the gerber files and schematics of the pcb required for production, but I unfortunately don't have the project files. I am attaching the image of the changes needed to be done to the pcb and I will need all of the production files for it as well. The main point of the changes is to reduce the length of it. The lead time is very important so please, if you can, include a rough estimate of time that you will need as well.
I need to redraw this diagram in Kicad. Currently, the board is on a single PCB, I would like each function to be on a single PCB connected to the next in a modular manner like the attached image. As per the attached picture, I would also like to change the flat cable insertion with an adapter. Each module must be 60mm x 60mm and use non-SMD components but the classic through-hole ones.
