REFERENCE DESIGN
Figure 20: SE868 Family Reference Design
Along with power and grounds, the minimum signals required to operate the receiver
properly are the RF input signal and two digital I/O signals (TX0 and RX0).
TX and RX are UART lines with a default of 9600-8-N-1. They are used for message output
and command input. Be careful not to drive the RX line if the module is turned off.
Note: Please refer to Section 9 Electrical Interface for important
details.
