This is a LoRa Gateway board designed for FeatherWing ecosystem, based on Semtech SX1303 Digital Baseband Chip and Ublox EVA-7M GPS module. Board schematic is largely based on the SX1303 reference design, and this board is designed for 915Mhz operation.
This Design is still in development process, please use with caution
MCU software is also in development process
You can find it here https://github.com/will127534/SX1302_Arduino_Library
SX1303 uses the SPI bus and two GPIO (CS and Reset on D5 and D6) on the FeatherWing to communicate with host MCU
GPS module uses the UART pins and a GPIO for pulse-per-second output on A5.
KiCad v5.99 is used to design the board, and JLCPCB to manufactured the board. I'm pretty noob about the KiCad stuff, so any feedback is welcome.
I sourced most parts from Mouser, here is the parts list: https://www.mouser.com/ProjectManager/ProjectDetail.aspx?AccessID=11549c8008
Note: SMA connector is not included, because it is related to the board thickness your are using, I'm using 1mm 4 layer pcb, and I can't find the connector on Mouser.
