RP2350 Stamp-Hole Microcontroller Board

Development board built on the RP2350A microcontroller, featuring dual-core processing (ARM + Hazard3 RISC-V) with up to 150MHz clock frequency. Includes 520KB RAM and 4MB flash memory. On-chip peripherals consist of stable clock sources, multiple hardware timers, and integrated temperature sensing. Communication handled via USB Type-C port supporting USB 1.1 host and device capabilities. Designed for minimal power use and straightforward integration into custom hardware using its stamp-hole edge design. Fully aligned with RP2350A documentation and pinout conventions. The temperature sensor provides continuous monitoring with ±2°C accuracy across operating range, accessible without external calibration. Hardware timers support one-shot, periodic, and pulse-width measurement modes with interrupt or DMA trigger options. USB interface uses differential pair routing matched to 90Ω impedance, meeting USB 1.1 signal integrity requirements without additional termination resistors. Commonly adopted for teaching embedded systems with exposure to emerging open-source ISAs; rapid iteration of sensor-driven prototypes requiring local intelligence and environmental adaptation; and embedded control units in energy-efficient appliances where thermal headroom and predictable timing affect certification compliance and user experience.
