RP2350 Raspberry 2MB Pi Core2350B1 Kit

The Waveshare Core2350B1 kit is a compact high-performance microcontroller board based on the Raspberry Pi RP2350B. The innovative chip offers a unique dual-core and dual-architecture design with either two ARM Cortex-M33 cores or two Hazard3 RISC-V cores at up to 150 MHz clock speed. With 2 MB PSRAM, this variant offers the largest available memory in the Core2350B series for particularly memory-intensive applications. The kit includes a USB port adapter with a Type-C connector and an FFC connection cable for instant startup.

Features:

• Dual-architecture allows choice between ARM Cortex-M33 and RISC-V Hazard3 cores
• 2 MB PSRAM provides maximum memory for demanding applications like image processing
• Compact size of only 25.4 × 25.4 mm is ideal for space-critical projects
• 48 GPIO pins offer extensive connectivity for peripherals and sensors
• USB-C adapter included enables immediate operation without additional accessories
• 12 programmable PIO state machines allow the implementation of custom protocols

Application examples:

• Image processing and graphics buffering for display applications
• Machine learning inference with large models at microcontroller level
• Audio processing with extensive sample buffers
• Data logger with high storage capacity for long-term recordings
• Embedded web server with dynamic content
