This is a SAM D21GxxL, QFN-48 Microcontroller with 48 pins

Connector Header Through Hole 10 position 0.050" pin header 2x5 1.27mm The Harwin M50-3500542 is a 1.27 mm pitch (0.05") 2×5 male pin header from the Harwin Archer M50 series, designed for board-to-board or cable-to-board interconnections. It is a through-hole, vertical PCB connector commonly used in embedded systems, debug interfaces (SWD/JTAG), and compact electronics where high-density signal routing is required. This connector provides a reliable low-profile interconnect solution with gold-plated contacts for good signal integrity and durability in industrial environments. Key Features Connector Type 2×5 (10-position) male pin header Dual-row configuration Pitch 1.27 mm (0.05") fine pitch for high-density PCB layouts Mounting Type Through-hole vertical PCB mount Contact Type Male square pins (0.4 mm typical) Electrical Rating Up to 1A per contact Contact Plating Gold plated mating area Tin plated tail for soldering Operating Temperature -40 °C to +105 °C Housing Material High-temperature thermoplastic (UL94 V-0 rated) Stacking / Mating Heights Multiple height options (approx. 3.2 mm to 6.2 mm) for flexible board stacking Compact Design Designed for high-density embedded PCB layouts Typical Applications ARM Cortex SWD / JTAG debug headers Embedded development boards Board-to-board mezzanine connections Industrial control electronics Compact IoT and MCU systems #CommonPartsLibrary #Connector #Header

Wio-E5-LE module has a single-core STM32WLE5JC chip, Cortex M4 MCU, and SX126X. It uses 84% less power for transmission compared to the Wio-E5. The ultra-low power consumption of the Wio-E5-LE makes it very energy efficient, this power-saving design makes the Wio-E5-LE well-suited for applications needing minimal power usage.
