Schematics Reference
RAK2287 card refers to Semtech's reference design of SX1302. The SPI interface or USB
interface converts SPI to USB2.0 by STM32L412Kx, and can be used on PCIE connector.
The next figure shows the minimum application schematic of RAK2287 card. You should
use it at least 3.3V/1A DC power, connect SPI interface or USB interface to the main
processor
.
