12V DC voltage meter system + I2C.

Just a simple project which is now discovered that the traces for SCL and SDA has to be much larger to be equal in 22-gauge wire or the pull up resistors fails. Thin traces will not work. Missed tech step. This is a concept board. 4 banks of 12VDC (4S 20P) arrangement can be monitored using a simple Arduino Nano processor or any 5-volt equivalent or better processor. As long as 5 volts are accepted in single and power.

    nice pcb thanks everyone.
    Very good PCBA quality. All 5 pcba pcbs are working with not issues. Extra care was done by adding more solder for the USB C anchors.
    Great PCBs, did exactly what I needed. Got the first PicoZX up and running very quickly. The PCBs were perfect quality, I'm very happy with my order and am already thinking about what project to do ne...
    Nice feature of multi-color PCB
    On time, no issues. The final product tested out fine, I built 10 boards and all worked great.
    This was a difficult part to fabricate (small mesh and bends near the mesh) the part is (as expected) a little bit out of shape because of the heat during production but that will be fixed as soon as ...
    Perfect as usual
    This is my third order of PCBs for my single board computer projects. Excellent quality of PCB manufacturing, fast delivery, user-friendly website with excellent navigation and a selection of options ...
