Onboard FPC 8pin connector; USB TypeC port supported via adapter board; castellated module allows soldering directly to carrier boards. USB 1.1 with device and host support; lowpower sleep and dormant modes; draganddrop programming via USB mass storage; up to 20 multifunction GPIO pins. Supports FSK, GFSK, and LoRa modulation; improved antiblocking and ultralong distance communication; preamble detection with CRC; data packet engine up to 256 bytes. Use scenarios Remote environmental monitoring and IoT deployments in Europe or Asia: LoRa enables longrange communication from field sensors (soil moisture, temperature, humidity, etc.) to gateways, reducing wiring and infrastructure needs. Asset tracking and logistics: LoRabased wireless links cover wide areas for tracking assets across campuses, facilities, or transit routes; USB mass storage programming simplifies field updates; up to 20 GPIO pins support additional sensors or interfaces. Industrial edge computing and rapid prototyping: Dualcore MCU with flexible timing and longrange radio enables compact edge devices and prototypes; USB host support allows connection to peripherals while using draganddrop programming for quick iteration.
