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 CMOS / TTL logic
level serial sources. The module can be directly
connected to virtually any serial device including
microprocessors, RS-232 / RS-485 level
converters or Linx wireless RF modules. The QS
module is completely self contained so it 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 up to 3Mbps.
