LR Series Part Numbers
Linx Technologies’ new LR Series transmitter offers more stable performance over various
antenna loads and a higher data rate in the same package as the LC Series transmitter, but
the pin-out is slightly different. Pin 4 is the Level Adjust pin for both modules, but this gets
connected to ground on the LC and to Vcc on the LR. Pin 8 is ground on the LC and is
Power Down for the LR and should be connected to Vcc to activate the module. All other
pins are the same for both modules. For data sheets and user manuals, please see the Linx
website at www.linxtechnologies.com.
