Page 5: Data Transmission
“reserved” pins may remain suspended or pulled up by resistor to VCC. The upper rated voltage of module 433MHzFSK is 4.2v, if exceeded (e.g. 5v input), potential instability might be occurring, or malfunction might take place and even endanger the module, so it is not recommended to put this module directly into a 5v system. -
Page 6: Frequency Settings
Frequency settings on each channel are shown as follows: 433M: 430.26M-439.71M 868M: 860.50M-869.95M 915M: 915.18M-924.63M The difference between channels is 150 kHz, detailed channel frequency calculation (take 915M channel as an example, other frequency settings have the same calculation method © 2004-2008 Sure Electronics Inc.

For 433MHzFSK-A, it would always be in a reception status when awakened.
- Page 8 The following figure shows the connection of module and MCU in which PIN5, PIN6, PIN8 are optional connection. For 433MHzFSK-A, it’s unnecessary to connect PIN7, grounding PIN5 directly if ultra low consumption is not in use. Notes that “Busy Port” PIN6 cannot be pulled up directly to power supply.
