Small green PCB development board with integrated USB-A plug and castellated edges

LORDWORLD

LORDWORLD RP2040-One development board 4MB flash USB-A

SKU CH-FVNJ-8QH7H

Pico-like RP2040 board with onboard USB-A plug, 4 MB flash and dual-core Arm Cortex-M0+ running up to 133 MHz

  • Ready to code immediately with built-in USB-A plug
  • Expand projects using 4MB flash storage
  • Develop in C/C++ or MicroPython with full SDK
  • Prototype compact designs on castellated SMD module
  • Run dual-core Cortex-M0+ at up to 133 MHz

RP2040 microcontroller board with USB-A

This development board integrates the Raspberry Pi RP2040 dual-core Arm Cortex-M0+ processor running at up to 133 MHz. It is designed for makers and engineers who want a compact, breadboard-friendly module for embedded projects. The castellated edges allow direct surface-mount assembly into custom PCBs.

4 MB flash provides generous program space

The 4 MB onboard flash memory offers significantly more storage than standard Pico boards, accommodating larger firmware images and data logs. It comfortably handles complex MicroPython applications and C/C++ projects with multiple libraries. Very large multimedia assets or extensive local databases would exceed the available capacity.

USB-A plug enables cable-free connection

The built-in USB-A connector plugs directly into a host port without extra cables, simplifying power and data transfer during development. Castellated pads support reflow soldering for permanent integration into finished devices. Boards without castellations or with only micro-USB would not suit these mounting and connectivity needs.

Questions about this item

Will the board's USB-A plug work directly with the USB-A ports on my older laptop without needing an adapter cable?

Yes, the onboard USB-A plug connects straight to a standard USB-A port so no extra cable is required.

How can I verify the dual-core Arm Cortex M0+ processor is running at up to 133 MHz after I flash my first program?

The board enumerates as a USB mass-storage device when powered; a simple MicroPython script printing the clock frequency will confirm the 133 MHz operation.

Does the package include any headers or jumper wires for the castellated module pads, or must I source them separately?

Only the RP2040-One board itself is supplied; headers, jumper wires and any soldering materials for the castellated pads are not included.
