    Pin Assignments Module Description The Linx SDM-USB-QS module converts USB signals from a host, such USBDP as a PC or hub, into TTL logic level signals. This enables the module to USBDM be connected directly to microcontrollers (or Linx RF modules for wireless applications) or to RS-232 or RS-485 level converters for communication with legacy devices.
