Dualcore ARM M0+ processor with a flexible clock up to 150 MHz, 520 KB RAM, and 4 MB onboard flash memory. FPC 8pin connectors enable USB TypeC port compatibility with an adapter board for easy integration. Development board supports soldering directly to carrier boards, USB 1.1 device and host compatibility, and includes lowpower sleep and dormant modes for energy efficiency. Draganddrop programming via USB mass storage for straightforward firmware updates and deployment. I/O and peripherals 28 multifunction GPIO pins 2 x SPI 2 x I2C 2 x UART 4 x 12bit 16 x controllable channels Key benefits Clear path from prototyping to deployment with simple USBbased programming. Flexible timing up to 150 MHz supports a range of embedded applications. Onboard memory provides space for code, data, and peripheral drivers without external components. USB TypeC compatibility via adapter board simplifies connection to modern hosts and devices. Lowpower sleep and dormant modes enable energyefficient operation in batterypowered designs. Rich I/O and multiple interfaces make it suitable for sensor networks, control systems, and hobbyist projects. What makes it practical Direct solderability to carrier boards streamlines custom hardware development. USB 1.1 device/host compatibility supports a wide array of USB peripherals and host interfaces. The combination of GPIO count, multiple SPI/I2C/UART ports, and multiple analog/digital channels supports diverse sensing and control tasks in a compact form factor. Use scenarios Rapid sensor data logger: connect multiple I2C sensors and SPI devices, log data to onboard flash, and update firmware via USB mass storage. Embedded control prototype: develop with USB 1.1 host/device support, use 28 GPIOs and multiple UARTs to interface with actuators, motors, and humanmachine interfaces. Education and hobby projects: leverage the draganddrop programming workflow, lowpower modes, and flexible I/O to teach or experiment with embedded systems and hardware interfacing.
