This is for 2, the MCU board from the for that is based on the latest RP2350.The for 2 maintains complete pin-to-pin compatibility with its predecessor, the for . This ensures a seamless transition for existing projects and carrier boards, allowing users to leverage their existing investments and expertise. Developers can effortlessly migrate their code and hardware designs to the 2, benefiting from enhanced performance and expanded capabilities without the need for extensive modifications. The 2 comes with a Dual-Core ARM -M33 and a Dual-Core RISC-V Hazard3. Flexible clocking system, with configurable up to a maximum speed of 150MHz! This tiny MCU comes with a whopping 520 Kbyte of , an external QSPI Flash with a capacity of 4 MByte, and enhanced eXecute in Place (XIP v2). Larger RAM and Flash size enable you to write high-level programming languages like MicroPython and CircuitPython for 2. 2nd generation of for board comes with the following enhancements:CPU: Two Dual-Core CPU:Dual ARM -M33 Cores Dual RISC-V Hazard3 Cores System clock up to 150MHz : 520KByte 4MByte QSPI Flash Memory Comprehensive Security: ARM TrustZone, 8KB on-chip OTP Storage, Secure boot XIP v2 for better flash memory interface 12 PIO state machines (3 blocks) You can always connect the to any preferred computer with , for-macOS, and Linux that supports Python 3.0, yet connecting it with the Single Board Computer be perfect.
