Figure 6 and Figure 7 illustrate the use of an external antenna using the ANT1-M24LR16E
demonstration board.
• Figure 6 shows a possible direct connection of the Vout voltage coming from the ANT1-
M24LR16E antenna demo board on jumper JP1 to bypass the voltage regulator (U5).
• Figure 7 shows the connection of the Vout voltage coming from the ANT1-M24LR16E
antenna demo board on connector CN2 to use the voltage regulator (U5). Jumper JP1
must be set as shown in Figure 5.
