LoRa®，SF = 5 - 6 - 7 - 8 - 9 - 10 for BW = 250 kHz, LoRa®，SF = 5 - 6 - 7 - 8 - 9 - 10 - 11 for BW = 500 kHz; Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd. -
Page 9: Basic Application
At room temperature, the low voltage of the power supply is lower than the recommended value. The lower the voltage, the lower the output power; Due to antenna quality or poor matching between antenna and module. Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd. -
Page 10: Module Is Easy To Damage
Poor power supply may cause messy code. Make sure that the power supply is reliable; The extension line and feeder quality are poor or too long, so the bit error rate is high. Copyright ©2012–2019，Chengdu Ebyte Electronic Technology Co., Ltd. -
