USB Module Description
The Linx QS Series USB module allows the rapid addition of USB to virtually any device. Housed in a compact SMD package the QS module provides a complete solution for converting between USB and logic level serial sources. The module can be directly connected to virtually any serial device including microprocessors, RS232/RS485 level converters, or Linx wireless RF modules. The QS module is completely self contained and requires no external components, (except a USB jack) and includes all necessary firmware and drivers, freeing the designer from complicated programming. Power can be supplied externally or from the USB bus. Both USB 1.1 and USB 2.0 are supported at data rates to 3Mbps.
