PCB DESIGN TECHNIQUE AND PIN ASSIGNMENT TECHNIQUE WHICH CAN APPLY PATHS HAVING DIFFERENT FREQUENCIES TO ONE RF PIN IN LoRa MODULE

摘要

The present invention relates to a PCB design technique and a pin assignment technique which can apply paths having different frequencies to one RF pin in a LoRa module for minimizing a PCB type and maximizing the performance. To this end, the LoRa module can be operated through one RF pin to be applied to both domestic and Chinese uses by using one PCB design in the domestic use with a non-licensed frequency in a band of 920 MHz which is a high frequency, and in the Chinese use with a frequency in a band of 470-490 MHz and a band of 500-510 MHz which is a low frequency (LF), and an optimal module pin arrangement can be performed for a stable operation.;COPYRIGHT KIPO 2019
