    We need to make a gerber file for our pcb setup. it will be to contact 16 spring contacts and a set of two square eights pin contacts. :) The last two photos is of the original pcb we are trying to replicate. the problem with this one is that it only has eight spring contacts and only holds a sample that is 25x25mm we need it to have 16 contacts instead of eight and it being able to measure 8 points of a 100x40mm sample. the distance between the spring contacts should be 1cm center to center side ways. See the photos if you have any questions or send a question thru here.

Voltage and current rating of the solar panels: This information is crucial for determining the size of the cables that are needed for each configuration. 2. Cable insulation: Choose a suitable insulation material that can withstand high temperatures and UV radiation. 3. Cable length: The length of the cable between each panel and the junction box should be calculated to ensure that the correct cable size is used. 4. Number of strings: The number of cables that are needed for each configuration should be determined based on the number...

I want to measure +5PSI to -5PSI pressure value, with auto zero calibration. When there will no pressure on the pressure sensor that must be zero value at the initial condition. It should be strictly maintain. It can be set by auto zero calibration. I want to measure pressure precisely, so you need to do the coding with exact calculation.
