ICQUANZX HC-12 3.2-5.5V 433Mhz SI4463 Wireless Serial Port Module 1000m Replace Bluetooth

• Operating frequency range: 433.4-473.0 MHz
• Supply voltage: 3.2 V - 5.5 V. (If the modules work for a long time in emission state, it is recommended to chain a 1N 4007 diode at a supply voltage of more than 4.5 V to avoid the LDO module has a fever)
• Standard communication distance: approx. 600 m (communication distance is adjustable up to 1000 m, baud rate 5000 BPS).
• Standard no-load current: 16MA (modules in different working modes of different current)
• Mini size, only 27.8 mm x 14.4 mm x 4 mm.
