Using the RP2350 microcontroller chip Dual-core ARM-M33 processor, running at up to 150MHz with flexible clock Built-in 520KB SRAM and 4MB onboard Flash True castellated hole design, can be directly soldered and integrated into the user's self-designed baseboard USB 1.1 host and device support The RP2350-Core-A micro-type development board uses the RP2350 developed by Raspberry Pi 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 footprint. Whether you are a beginner or an experienced developer, the RP2350-Core-A is an excellent choice for your next project. Supports low-power sleep and hibernation modes Can be identified as a mass storage device through USB for drag-and-drop program loading The USB interface can be extended via an adapter board Note: Due to different production batches, the silkscreen printing or appearance may vary slightly, which does not affect functionality Specifications: RP2350-Core-A-Kit-Soldered Color: Black Material: PCB Package Contents: 1 x Soldered Development Board 1 x USB Cable Only the above package content is included; other products are not included Note: Lighting and display differences may cause the color in the image to differ slightly from the actual item. Measurement error is +/- 1-3 cm
