LORDWORLD RP2040-One Development Board 4MB Flash

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.
