Who this is for Electronic engineers, firmware developers, and educators who need a compact, flexible microcontroller board for advanced projects and training. Ideal when you require extensive I/O, onboard processing, and easy integration into custom baseboards. Key benefits — why you need this board Dualarchitecture processing: RP2350A chip combines doublecored ARM and Hazard3 RISCV processors to handle realtime control and higherlevel tasks concurrently. Reliable performance: Processors run up to 150 MHz for responsive control, data handling, and multitasking. Ready for integration: TypeC power/data, USB 1.1 host/device support, and a stamphole design let you mount or embed the board into custom hardware quickly. Compact, capable memory: 520KB and 4MB onboard flash provides space for firmware, logging, and application code without immediate external storage. Flexible I/O and programmability: Extensive GPIO options make the board suitable for sensors, actuators, robotics, and programmable machines while keeping development accessible for teams and students. Lowpower operation: Designed for energyconscious applications and prototypes that run on limited power budgets. Important features at a glance Processor: RP2350A with dualcore, dualarchitecture (ARM + Hazard3 RISCV) Clock: Up to 150 MHz Memory/Flash: 520KB and 4MB onboard flashing Connectivity: USB TypeC, USB 1.1 host/device Mechanical: Stamphole design for seamless integration into custom baseboards Power: Lowpower support for batteryoperated or energyefficient systems I/O: Extensive GPIO options for sensors, motors, displays, and peripherals Compatibility and usage Compatible with common development tools and workflows used by electronic engineers and educators (standard USB connectivity for programming and debugging). Designed to be soldered or mounted into custom baseboards via stamp holes for prototypetoproduct progression. Practical use scenarios 1) Smart home prototype: Connect environmental sensors, relays, and a wireless module to run local automation logic on the ARM core while offloading deterministic timing or safety checks to the Hazard3 RISCV core. 2) Educational robotics platform: Use the board to teach embedded systems — students can program motion control, sensor fusion, and communication interfaces while learning multicore coordination. 3) Industrial control or datalogging device: Deploy as a compact controller with local flash for logs and firmware, USB host/device for peripherals, and lowpower modes for intermittent operation. What it solves Reduces hardware complexity by combining two processor architectures on one board for mixed workloads. Simplifies integration into custom hardware through a stamphole footprint and standard TypeC connectivity. Provides adequate onboard memory and flash to develop and test complete application firmware without immediate external storage. Ordering and integration tips Use the stamp holes to secure and align the board on your carrier or product PCB. Connect via USB TypeC for straightforward programming and power. Verify USB 1.1 compatibility for older peripherals if needed. Plan software tasks between the ARM and Hazard3 RISCV cores to maximize responsiveness and deterministic control where required.
