RAK3172-SIP (Advice on PCB Error)


On a new design for the RAK372-SIP a schematic error has occurred where the +3.3V Rail has been connected to the VLXSMPS Inductor. The PCBs have not been populated yet.

From the documentation the inductor can be omitted with slightly higher power requirement.

Can a suggestion be made on the best way forward regarding Absolute Max Ratings on the pin VFBSMPS etc

Thank You

As the RAK3172-SiP is internally a STM32WLE5, the operating conditions should be 1.4 to 3.6V
