What would these LF and RF be? Are two antennas necessary? Where can I find the schematic or gerber of this attached slide plate?
Hello,
L5---LF
E1---RF
The LF receiver block allows the TPMS to receive signals at 125kHz.
The RF transmitter generates a radio frequency (RF) signal to send the data.
You will find the Schematic and Gerber files in the following link: NTM88 sub-GHz Schematic and Gerber files
