G-NiceRF SX1280 Breakout (2.4GHz LoRa!)

  • Sale
  • Regular price $ 19.99


What is the Semtech SX1280? It’s a 2.4GHz version of the extremely popular SX127x LoRa line. We carry G-NiceRF variant that can transmit at an impressive 100mW.

The G-NiceRF module comes completely shielded, for improved RF performance. Also included is an SMA connector and headers.

The SX1280 has faster LoRa modes and a new modulation technique called FLRC, which stands for Fast Long Range Communication, which is a spread spectrum mode with FEC (forward error correction). It also supports traditional modes such as GFSK and FSK. A "BLE compatible" PHY is also supported, but you would have to write your own BLE stack.

Most interestingly, it also can determine the distance between two transmitters with a reasonable amount of accuracy! Stuart Robinson has a great write up on his range testing, which was accurate to about 100m or so. He also had an impressive 89km of range while operating on a balloon.

In addition to an SPI mode, it also can support serial UART, making the development process a little higher for high speed data applications.
