Note
- Wireless data transmission requires two or more modules to set up wireless link. Each module itself supports sending and receiving, but at the same time can only work in transmit mode or receive mode.
- Maximum operating voltage of this module 3.6V. CE pin could not survice voltage over 3.6V. Otherwise the module might be damaged.
- Transmission distance varies according to the testing enviornment. We tested it in open area.
