SC189CSKTRT Frequently Asked Questions (FAQs)

  • A 4-layer PCB with a solid ground plane and a separate power plane is recommended. Keep the RF traces as short as possible and use a 50-ohm microstrip line for the antenna connection.
  • Ensure that the devices are configured to use the same frequency band, spreading factor, and coding rate. Also, verify that the devices are within range and have a clear line of sight.
  • The maximum transmit power is +20 dBm. You can adjust the transmit power by using the SX1262's built-in power amplifier and configuring the PA_BOOST pin.
  • Use the SX1262's built-in frequency hopping engine and configure the frequency hopping parameters using the LoRaWAN protocol. You can also use the device's API to implement custom frequency hopping schemes.
  • A quarter-wave monopole antenna or a dipole antenna with a 50-ohm impedance is recommended. The antenna should be designed to operate at the desired frequency band (e.g., 868 MHz or 915 MHz).
