The module operates from 1.8 V to 3.6 V DC, with 3.3 V recommended for typical use.
The antenna must be placed outside any metal enclosure and kept away from system ground to avoid severe signal attenuation.
In open space the module can transmit over 100 meters at a data rate of 2.4 Kbps.
Handle the module in an ESD‑protected area, keep it dry, avoid liquid contact, use a separate stable power supply, and do not exceed the specified voltage range.
