WeAct Studio RP2350A_V20 Microcontroller Board with Dual-Core Raspberry Pi RP2350A SoC and ARM Cortex-M33/RISC-V Cores

The WeAct Studio RP2350A_V20 is an affordable microcontroller board based on the Raspberry Pi RP2350A. It shares a similar design to the official Raspberry Pi Pico 2 but features a black PCB, a USB Type-C port for power and programming (v1.1 device connector), and comes with either 4MB or 16MB of onboard QSPI flash along with 520KB of on-chip SRAM.

The RP2350A microcontroller offers robust security features, built around ARM TrustZone for Cortex-M. It includes signed boot support, 8KB of anti-fuse OTP for key storage, SHA-256 acceleration, a hardware true random number generator (TRNG), and fast glitch detection. These security features, including the secure boot ROM, are extensively documented and openly available to all users.

One of the standout features of the RP2350A is its unique dual-core, dual-architecture design. Developers can choose between two ARM Cortex-M33 cores or two Hazard3 RISC-V cores, providing the flexibility to experiment with RISC-V architecture in a stable and well-supported environment.
