Description: There is an antenna pedestal ANT1 on the module. Using 433M frequency band external connect antenna. with antenna welded hole ANT2, convenient for users to weld spring antenna. Power supply voltage: 3.2-5.5 V.(if the modules working long hours in emission state, suggested that when the power supply voltage is more than 4.5V, you need concatenating a 1N4007 diode to avoid module built-in LDO got fever) Default communication distance : about 600 m (communication distance is adjustable up to 1000 m, air baud rate 5000 BPS). Default idle current: 16 ma (different working mode, different current). Operating frequency range (433.4 473.0 MHz, as many as 100 communication channel) maximum 100mw ransmitting power(can be set) Module supporting software upgrades. Default factory Settings: working mode FU3, baud rate 9600 BPS, communication channel CH001 (433.4 M) Specification: Interface protocol: UART/TTL Transmit power: -1dBm to 20dBm Material: electronic components Size: approx. 27.8×14.4×4mm x 1 x 0.56 x 0.16inch Package Includes: 1 Piece HC-12 SI4463 Wireless Serial Port Module Note: HC-11 cannot communicate with HC-12; they work independently and in pairs. Including antenna cap, not including spring antenna
