Raspberry Pi unveils the Pico 2 for just $5
Summary
It includes a comprehensive security architecture built around Arm TrustZone for Cortex-M, as well as features like signed boot support, SHA-256 acceleration, a true random number generator (TRNG), and 8KB of antifuse one-time-programmable (OTP) memory. In addition to its robust processing power, the RP2350 introduces new interfacing capabilities, such as twelve upgraded Programmable I/O (PIO) state machines and a new HSTX peripheral for high-speed data transmission. The Pico 2 is already in full-rate production, and while initial stock may be limited, Raspberry Pi is working closely with its manufacturing partner, Sony, to ensure steady availability. This feature opens the door for developers to experiment with the RISC-V architecture in a stable, well-supported environment, potentially popularising the Hazard3 core as a versatile, open-source option for other devices. To encourage the community’s involvement, Raspberry Pi has partnered with the DEF CON hacking convention, providing RP2350-powered badges that offer a platform for experimenting with the new security architecture.
