Update information: Change chip from SI4463 to SI4438 (Shipped from 11.26.2019)
Note: HC-11 cannot communicate with the HC-12, they work independently, used in pairs.
Features:
1. Supply voltage: 3.2V~5.5V. (If the module you want to work long hours in the emission state, it is recommended that when the supply voltage exceeds 4.5V threaded a 1N4007 diode to prevent module built-in LDO heated)
2. Default address range (open field test): About 600m (maximum communication distance adjustable reach 1000m, the baud rate is 500bps)
3. Default idle current: 16MA (In different working modes operating current is different)
4. Module dimensions: 27.8 x 14.4 x 4mm
5. Operating frequency range: 433.4-473.0MHz, up to 100 channels of communication
6. The maximum transmit power
