Gateway module features:
1. On-board Semtech SX1302/3 baseband processor and SX1250 RF front-end chipset
2. On-board PA and LNA, with +26 dBm transmit power and -141 dBm receive sensitivity
3. The SX1303 supports fine-grained timestamping, enabling network positioning based on Time Difference of Arrival (TDOA)
4. Mini-PCIe form factor with 52-pin header, facilitating integration into various embedded systems
5. Four onboard LED indicators for easy monitoring of module operating status
Expansion board features:
1. Based on the Raspberry Pi 40-pin GPIO interface, compatible with Raspberry Pi series motherboards
2. On-board L76K module supporting GPS and Beidou, providing precise clock and positioning coordinates for the gateway module
