Package Comparison

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.
