We need to design a custom PCB to mount a Particle P1 chip, you should use CadSoft Eagle and work with our requirements to produce a custom PCB that can be manufactured. Previous experience in this field highly desired. https://docs.particle.io/guide/how-to-build-a-product/pcb-design/#pcb-design-resources I will provide a breadboard layout. I am using a Servo, a switch, a button and an LED, pretty simple circuit.

Objective – To create a PCB for custom sized LCD screen of dimension 110 mm X 1040 mm by connecting 5 individual screens of 100 mm X 200 mm dimension Example - Our product is a stretched bar type lcd for advertisement on shelfs. You can refer to a video of the same on this link - https://www.youtube.com/watch?v=0E4SoonekWw & https://www.youtube.com/watch?v=jhWDGvphdiM Also if you need more clarity, you can refer to data sheet from a parallel vendor who makes this product- http://www.display-solution.com/en/products/intelligent_tfts/mcm_multi_cell_monitors.html Attached is a basic sketch of the final product’s dimensions and the individual screens. Functionality on LCD 1) Video display of most common formats 2) Option of connecting several screens together (through USB or through other connectors) 3) Video streaming through 3G network

I need someone who can replicate the attached FPCB with a IC. The IC has a simple function so it shouldn't be to hard to create. I have the Gerber files of the board. I also have the board. This board will be put into a controller which has roughly 20 buttons on it. I want to add extra tact switches to this controller which is what this FPCB is for. The tact switches are connected to the FPCB board via M1 M2 M3 M4 (see picture). The 37 conductive points connect to the controller so that we are able to re route all of the buttons from the controller through the IC to the M1 - M4 points. The function of the IC: 1) The board has 37 conductive points as you can see from picture. 2) 5 or 6 of them points are for ground. 3) The rest are button functions. eg Button 1, Button 2, B3, B4, etc.. 4) M1, M2, M3, and M4 on the board will be connected to external tact switches. when i hold down tact switch for 10 seconds along with another button on the controller, tact switch becomes that button. eg, if i hold down button 5 on the controller with M1 tact switch, M1 tact switch becomes button 5. The LED then lights to notify the user of the change. I have the gerber files of the board without the IC which i will need adapted slightly. I also need to add the IC and the software for the IC. Ps i hope ive described that well enough. Any questions are welcome.

I need a breadboard I can take and get manufactured that combines the below devices. Smallest size possible is the goal. It also needs to be able to take 12 v. in and run a 12v solenoid valve and 5v flowmeter that has an interrupt. 1. Arduino Nano https://www.arduino.cc/en/Main/ArduinoBoardNano 2.

1. around 300 words, 2. theme is about solutions to solve the problems in pcb designing or PCB assembly, it should list the common problems in pcb design OR PCB Assembly, and measures to solve or avoid them 3, each article should include 1~3 pictures to better explain the subject pictures should not be download from web, should be your own PCB layout picture or other pcb picture, it can be just a screenshot which helps explain what you want to say 4. it should have a proper title. 5. 100% pass copyscape. http://copyscape.com/ If you have much experience in PCB design or assembly, welcome.
