@danielm said in LoRa module with TXCO: What difference in radio performance can be expected for L04 vs L01? SX127x chips offer lower bandwidth modes than 125kHz but you need a TXCO to use them. In LoRaWAN lower bandwidth not used to keep device prices low, but it can be usefull in other P2P or mesh network applications. Of course you need a Pycom firmware also which supports it in RAW LoRa mode.
