Introduction

LoRa, hc12, hc-12

  • Frequency band is from 433.4 MHz to 473.0 MHz
  • 100 channels with a stepping of 400 KHz between each channel
  • Transmitting power is from -1dBm (0.79mW) to 20dBm (100mW). A half-duplex 20 dBm (100 mW) transmitter
  • Receiving sensitivity is from -117dBm (0.019pW) to -100dBm (10pW)

Connect a 22 µF to 1 mF reservoir capacitor in parallel with the HC-12 "Gnd" and "Vcc" pins.
