FPC 8pin connectors adapt to a USB TypeC port via an adapter board for reliable USBC connectivity and flexible signal routing. Development board supports direct soldering to carrier boards, enabling USB 1.1 device and host configurations, with lowpower sleep and dormant modes for energy efficiency. On chip features include an accurate clock and timers, on‑chip temperature sensors, and accelerated floatingpoint libraries to improve performance in mathintensive tasks. 12x programmable I/O state machines provide flexible support for custom peripherals and actuator control. Draganddrop programming using mass storage over USB simplifies software deployment and testing. I/O and peripherals: 28x multifunction GPIO pins 2x SPI 2x I2C 2x UART 4x 12bit channels 16x controllable channels Use scenarios: USBC peripheral development: quickly prototype devices and host interactions by leveraging the USBC adapter and flexible GPIO/I2C/SPI/UART interfaces. Sensor data acquisition and control: use on‑chip temperature sensing, accurate timing, and multiple analog/digital channels to monitor environments or machinery. Educational and rapid prototyping: employ draganddrop programming over USB for fast iterations without complex toolchains, and expand with the wide set of I/O options for diverse projects.
