This high-performance development board features a 144-pin microcontroller and an integrated debugger/programmer for efficient prototyping. It supports USB re-enumeration for mass storage, virtual COM port, and debug port connectivity. The board is compatible with popular development environments including IAR, Keil, and GCC-based tools. Extensive software libraries and code examples are provided to accelerate project development. Expandable connectivity is available through a Zio connector and headers, allowing easy integration with a wide range of add-on boards. Hardware highlights include an external SMPS for Vcore supply (on "-P" versions), Ethernet interface (compliant with IEEE 802.3-2002 where supported by the MCU), USB OTG or Full-Speed Device, three user LEDs, two user buttons, a reset button, and a 32.768 kHz crystal oscillator. Power can be supplied via USB VBUS or an external source. The board includes USB Micro-AB, Ethernet RJ45 (if supported), and expansion connectors. This board is ideal for embedded prototyping and project development. Package includes: 1× development board. Note: Product appearance and printed text may vary slightly by batch; this does not affect functionality. Color may vary due to lighting and display differences. Measurement tolerance: ±1-3 cm.
