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.

The Linx CMD-KEY#-***-xxx Keyfob transmitter is ideal for general-purpose remote control and command appli cations. It has been pre-certified for FCC Part 15, Industry Canada, and European CE (433MHz only) compliance, reducing development costs and time to market. Available in 315, 418 (standard), or 433.92MHz, this stylish and compact remote has a range of up to 750 feet when combined with the LR Series receiver. The Keyfob can be configured with 1 to 5 buttons and the keypad and labeling can be modified to meet specific customer requirements. Selectable addressing provides security and allows the creation of up to 1,024 distinct transmitterreceiver relationships. The Keyfob is available in black, white, or translucent colors. The transmission can be decoded using a matching Linx Function Module, KH Series receiver / decoder, or an LR or LT Series receiver paired with a decoder IC or microcontroller. The unit operates from a single 3V CR2032 lithium button cell.
