Sparkfun Raspberry Pi Pico 2

The Raspberry Pi Pico 2 is a versatile $5 microcontroller board that offers a robust upgrade from its predecessors. Powered by the new RP2350 microcontroller, it boasts a higher core clock speed, double the on-chip SRAM, and double the on-board flash memory. With advanced Arm cores, optional RISC-V cores, enhanced security features, and improved interfacing capabilities, it maintains compatibility with earlier Raspberry Pi Pico models while delivering enhanced performance.

The board's comprehensive security architecture is a standout feature, centered around Arm TrustZone for Cortex-M. It includes signed boot, 8KB of antifuse OTP for key storage, SHA-256 acceleration, a hardware true random number generator (TRNG), and fast glitch detectors. These features, along with a secure boot ROM, are thoroughly documented and accessible to all users, ensuring transparency and confidence for professional integration.

One of the unique properties of the RP2350 is its dual-core, dual-architecture capability, allowing users to select between two Arm Cortex-M33 cores or two open-hardware Hazard3 RISC-V cores. This flexibility is ideal for developers who want to experiment with different architectures in their projects.

The board is programmable in both C/C++ and Python, making it accessible for a wide range of users, from hobbyists to professional developers. With detailed documentation available, the Raspberry Pi Pico 2 serves as an excellent platform for microcontroller development, whether for educational purposes, prototyping, or integrating into commercial products.
