Description

The Waveshare RP2350-Zero-CM Mini Development Board is engineered for developers requiring a high-performance, space-efficient microcontroller platform. Its core is the Raspberry Pi RP2350A, which uniquely offers a choice between dual Arm Cortex-M33 cores or dual Hazard 3 RISC-V cores, providing architectural flexibility for different firmware toolchains and performance needs. The board’s compact, castellated-edge design is a key feature, allowing it to be directly soldered as a surface-mount component onto a custom PCB, eliminating connectors and saving significant vertical space.

With 520KB of SRAM and 2MB of onboard Flash, the board supports complex embedded applications. Its extensive peripheral set, including programmable I/O (PIO) state machines, enables precise timing control for custom protocols without CPU overhead. Power management is handled via the USB-C port, which also serves as the primary programming interface using a simple drag-and-drop method, streamlining the development workflow for rapid prototyping and deployment in IoT nodes, industrial controllers, and compact automation devices.

Key Features

  • Dual-core, dual-architecture RP2350A SoC enables development for both Arm Cortex-M33 and RISC-V ecosystems.

Frequently Asked Questions

How do I program the Waveshare RP2350-Zero-CM board?

The board is programmed via its USB Type-C male port using a drag-and-drop method. Connect it to a computer, and it will appear as a USB mass storage device. Simply copy your compiled UF2 firmware file onto this drive, and the board will automatically reset and run the new code. This eliminates the need for external programmers and works with the official Raspberry Pi Pico C/C++ SDK or MicroPython toolchains.

What is the benefit of the castellated module edge design?

The castellated (half-hole) edge allows the entire RP2350-Zero-CM board to be directly surface-mounted (SMD) onto your own custom carrier PCB. This saves vertical space by removing the need for headers or sockets, creates a more robust mechanical connection, and enables the creation of ultra-compact final products. It is ideal for integrating the microcontroller as a core component in a finished device.

Can I choose between the Arm and RISC-V cores on the RP2350A?

Yes, the Raspberry Pi RP2350A SoC features a unique dual-core, dual-architecture design. You can configure your firmware project to utilize either the dual Arm Cortex-M33 cores or the dual Hazard 3 RISC-V cores. The choice is made at the software level by selecting the appropriate target in your build system (e.g., the Raspberry Pi Pico SDK), allowing you to leverage the tools and libraries specific to each architecture.

What power supply is required and what are the sleep currents?

The board is powered exclusively via the onboard USB Type-C male connector, accepting standard 5V USB power. While exact sleep current figures are not specified, the RP2350A microcontroller supports low-power sleep and dormant modes, which significantly reduce current consumption to microamp levels. This makes the board suitable for battery-powered applications where extending operational life between charges is critical.
