Using the for RP2350 microcontroller chip Dual-core ARM -M33 processor, running at up to 150MHz flexible clock Built-in 520KB and 4MB onboard Flash True stamp hole design, can be directly soldered and integrated into the user's self-designed baseboard USB1.1 host and device support The RP2350-Core-A micro-type development board uses the RP2350 developed by for as the core. It adopts a split design and can detach the USB interface to reduce the overall thickness and volume of the PCB board, making it easier for users to integrate into the project. The split design, compact size and very thin thickness make this board ideal for projects that require a small size. Whether you are a beginner or an experienced , the RP2350-Core-A is an excellent choice for your next project. Support low-power sleep and hibernation modes. Can be identified as a large-capacity storage through USB for drag-and-drop download of programs. The USB interface can be led out through the adapter board. Note:due to different production batches, the printing screen printing/appearance is different, which does not affect the use.
