HC-12 Wireless Transceiver Long Range Module 433Mhz 1000m


  • Wireless communication frequency band is 433Mhz
  • Multiple types of serial port transparent transmission modes have respective features, and the mode is changed by command
  • Low current consumption; the idle current is 80?A, 3.5mA or 22mA, depending on the selected mode
  • The number of bytes sent to serial port of module unlimited to one time
  • All functions and parameters are changed by command, and can be saved in case of power failure
  • Supply voltage 3.2V ~ 5.5V. (If you want to work in the module launch state for a long time, it is recommended when the supply voltage exceeds 4.5V series with a 1N4007 diode, to avoid heating module built LDO)
  • Default communication distance (open test): about 600m (adjustable to achieve the maximum communication distance of 1000m, the air baud rate 5000bps)
  • The default idle current: 16MA (modules in different operating current of the different operating modes)
  • Module Size: 27.8mm × 14.4mm × 4mm
  • Operating frequency range (433.4-473.0MHz, up to 100 communication channels) Maximum 100mW transmit power (can be set)
  • The module supports software upgrades. (We provide customers with software upgrades)
  • The default factory settings: operating mode FU3, baud rate 9600bps, communication channel CH001 (433.4M)
