• Increased I/O and Memory: Compared to the original Pico, the Pico 2 offers more GPIO pins, additional ADC channels, and higher SRAM, providing greater versatility and capability.
• Advanced Security Features: With support for Arm TrustZone and secure boot, the Pico 2 provides enhanced security for sensitive applications.
• Improved Power Efficiency: The Pico 2 supports low-power sleep states with optional SRAM retention, minimizing power consumption.

Development and Support

The Raspberry Pi Pico 2 retains compatibility with existing C/C++ and Python SDKs used for the original Pico, along with added security features and a new toolchain for RISC-V development. Comprehensive documentation and resources are available on the Raspberry Pi GitHub and documentation website.

Availability and Pricing

The Raspberry Pi Pico 2 is priced at $5 per unit before taxes and shipping, a modest increase from the original Pico’s $4 price. It is available for purchase individually or in bulk (480-unit reels) and will remain in production until at least January 2040. Top of Form
