An FT232 device is connected to a MAX483 RS-485 transciever +which allows for a longer distance multidrop communications bus. + +The schematic is based on the example shown in the FT232 datasheet. + +## Notes + +Manufactured by SeeedStudio Aug 2017. Board is fine except the mounting +holes in the USB micro connector footprint have been plated (they are +correctly marked as unplated). This allows the shell to short with Vcc +so it was necessary to lightly drill the holes to disconnect them from +copper on both top and bottom. -- 2.23.0
