LORDWORLD RP2040-One Development Board 4MB Flash

SKU CH-J59D-W9KW0

Dual-core RP2040 microcontroller board with 4MB Flash, 264KB SRAM, 29 GPIO pins, castellated edges for direct soldering, and USB 1.1 drag-and-drop programming

  • Dual-core Cortex-M0+ up to 133 MHz for responsive real-time tasks
  • 4 MB on-board Flash and 264 KB SRAM store larger firmware images
  • Castellated edges enable direct SMD mounting on carrier boards
  • 29 multi-function GPIO pins with 20 on the edge header for flexible I/O
  • Drag-and-drop programming over USB 1.1 mass storage simplifies development

RP2040 Microcontroller Board

The LORDWORLD RP2040-One is a development board built around the Raspberry Pi RP2040 microcontroller chip. It features a dual-core Arm Cortex-M0+ processor running up to 133 MHz with 264KB of SRAM and 4MB of on-board Flash memory. The castellated module design allows the board to be soldered directly onto carrier boards for embedded integration.

For SMD Integration and USB Projects

This board suits developers creating surface-mount applications who need drag-and-drop programming via USB mass storage. It also fits low-power designs that use sleep and dormant modes. Builders requiring wireless connectivity such as Wi-Fi or Bluetooth should look elsewhere, as the board provides only wired USB 1.1 and GPIO interfaces. Projects needing more than 4MB of Flash storage or a different processor architecture will need alternative hardware.

Embedded Carrier Board Design

The castellated edges enable direct soldering to a custom carrier PCB, freeing up space by eliminating pin headers and sockets. The USB 1.1 port provides both device and host support for peripheral communication or firmware updates. With 29 multi-function GPIO pins — 20 accessible via the edge pinout and the rest via solder points — the board connects to 2 SPI, 2 I2C, 2 UART, 4 ADC channels, and 16 PWM channels for sensors, actuators, and displays.

Questions about this item

What computer interface do I need to power and program the RP2040-One?

A USB 1.1 port on your computer provides both power and the mass-storage programming interface.

Will the castellated edges let me keep using my existing 0.1-inch header protoboards?

The castellated module is designed for direct SMD soldering to carrier boards, not for plugging into standard 0.1-inch headers.

How do I confirm the board is running code after a drag-and-drop flash?

After the board remounts as a mass-storage device, the on-board LED connected to a GPIO pin will blink or stay lit if the flashed program drives it.
