RAKwireless RAK3272LP-SiP Breakout Board

RAK3272-SiP and RAK3272LP-SiP Breakout Boards were designed to allow easy access to the RAK3172-SiP/RAK3172LP-SiP (opens new window)module pins to simplify development and testing. The two SiP module variants use different RF output paths to optimize current consumption depending on the application. RAK3172-SiP uses RFO_HP while RAK3172LP-SiP uses the RFO_LP on the STM32WL SoC transceiver.
