I would like to make a IoT PCB board based on the Beaglebone black, but without HDMI. I want to add a bunch of sensors, in addition to a GSM module etc. I am not an expert PCB designer nor I got the schematics, but I know what are the things that should go on the board.
So, could anyone please recommend a PCB designing service that is good for such project?
Thanks in advance.
