Three green RP2040-Zero boards with USB-C connectors

MCDODO

MCDODO RP2040-Zero USB-C Development Board 3PCS

SKU CH-GZ29-WPASR

Pack of three RP2040-based development boards with USB-C, dual-core Cortex M0+ at 133 MHz, 264 KB SRAM and 2 MB flash

  • Product typeSingle Board Computers
  • Dual-core Cortex M0+ runs up to 133 MHz for responsive IoT control
  • 2 MB on-board Flash and 264 KB SRAM store firmware and data locally
  • USB-C connector enables drag-and-drop programming via mass storage
  • Castellated edges allow direct soldering onto custom carrier boards
  • Low-power sleep and dormant modes extend battery life in embedded projects

Compact USB-C microcontroller board

The MCDODO RP2040-Zero is a tiny development board built around a dual-core Arm Cortex M0+ processor running up to 133 MHz. It provides 264KB of SRAM and 2MB of on-board Flash memory. A USB-C connector and castellated edges allow direct soldering to carrier boards. It supports C/C++ and MicroPython with a complete open-source SDK.

Replaces larger Pico-style boards

This module suits makers who need the RP2040 core in a smaller footprint with a modern USB-C port. The jump is worth it when space is tight or when drag-and-drop mass-storage programming simplifies your workflow. Builders who need more GPIO pins or onboard peripherals should look at full-size alternatives.

Limited by USB 1.1 speeds

The board uses USB 1.1 with device and host support, so data transfer rates are modest. Low-power sleep and dormant modes help battery-operated projects, but high-throughput streaming is not practical. The castellated design eases integration, yet the USB interface remains the main bottleneck for external communication.

Questions about this item

What board dimensions and castellated edges must my carrier board accommodate?

The RP2040-Zero uses castellated edges for direct soldering to a carrier board; match the module footprint and pad pitch when designing your carrier.

How do I put the board into drag-and-drop programming mode over USB?

Hold the BOOTSEL button while plugging the USB-C cable into a host; the board appears as a mass-storage device so you can copy a UF2 file.

How often will the on-board 2MB Flash need replacement under normal write cycles?

The 2 MB Flash is rated for typical microcontroller endurance; it does not require scheduled replacement in standard development use.
