Summary:

  • The SX1262 generally offers better performance in terms of power consumption, sensitivity, and size, and supports a wider frequency range and IEEE 802.15.4g. It's a newer generation chip.
  • The SX1278 is an older, more established chip that is still suitable for many LoRa applications, particularly where cost is a primary concern and the advanced features of the SX1262 are not required.
