Accessories
1) Antenna
The antenna is very important for RF communication. We have many kinds of an antenna for the customer to choose, please contact the corresponding sales engineer for help.
★ Tips for antenna：
Don’t close to the ground, metal, magnet, big current；
If you are using the sucker antenna, pull the wire as straight as possible, the sucker foundation should stick with metal
2) USB bridge board
There are 3 type of USB bridge, which is SU108-TTL/ SU108-232 / SU108-485.SU108 -TTL is for TTL Interface, SU108-232 is for 232 Interface, SU108 - 485 is for 485 Interface. User should select the right USB bridge corresponding to the RF module.
