Note:

1 It is recommended to purchase more than 2 modules with the same frequency.

2 Please remove the jumper cap when using







First time use:

1 Remove the M0 jumper (very important)

2 Connect the antenna

3 Connect the DC 12V/24V power supply

4 Perform data transmission and reception test at baud rate 9600/N/8/1.
