[RC232] “Please confirm that: RC1180/1140 and 1190 have exactly the same foot print/pin out… The goal being to have only one PCB and the same print for the 3 modules. “ The fooprint and the software is exactly the same on these modules. Last Update: November 9, 2017 November 9, 2017 3637 RC232 Q&A Related Knowledge Base Posts -[RC232] In order to save costs, the customer need to make a only one board that can accept the different devices: RC1240 or RC1701 / RC1701HP or RC1740 / RC1740HP or RC1780 / RC1780HP or RC11x. Could you supply a final schematic for all pins (series resistors, pull-up, diode etc.)?[RC232] Have your heard of Modbus… do you have any experience..?[RC232] Can you please confirm the width of the PCB trace from the RF pin of the RC1140-RC232 to the copper pad we use to connect a wire antenna in order to achieve 50 ohms Z0? We’ve also done the layout so the power plane has a cutout below the microstrip.
