Round RP2040 board with 1.28 inch LCD and 30 GPIO headers

LORDWORLD

LORDWORLD RP2040 development board 1.28inch LCD 30 GPIO

SKU CH-S1YY-63FZN

A compact RP2040 board with a round 1.28-inch 240×240 IPS display, 30 GPIO pins on 1.27 mm headers, dual-core Cortex-M0+ at 133 MHz, 264 KB SRAM, 2 MB flash.

  • Dual-core Arm Cortex M0+ runs up to 133 MHz for responsive embedded tasks
  • 264 KB SRAM plus 2 MB Flash stores code and data on one board
  • 28 inch 240×240 IPS LCD shows 65 K colours in a compact round display
  • USB Type-C connector simplifies power and data with a modern reversible plug
  • 30 GPIO pins on 1.27 mm pitch female headers expand sensing and control options

RP2040 microcontroller board with round LCD

The LORDWORLD board centres on the RP2040 chip designed by Raspberry Pi in the United Kingdom. Its dual-core Arm Cortex M0+ processor runs at up to 133 MHz with 264 KB of SRAM and 2 MB of on-board Flash. A 1.28 inch 240×240 IPS LCD and 30 multi-function GPIO pins make it suited for wearable or handheld prototypes.

1.27 mm pitch GPIO header constraints

All 30 pins route through 1.27 mm female headers, yet several are already tied to the display, accelerometer, gyroscope and battery circuits. The wiki must be consulted before repurposing those lines. This reduces the freely available pin count for external sensors or actuators compared with an uncommitted header.

2 MB Flash and 264 KB SRAM headroom

The 2 MB Flash accommodates modest firmware, graphics assets and MicroPython scripts, while 264 KB SRAM handles runtime buffers for the 65 K-colour display. Complex real-time audio, heavy computer-vision models or large data-logging buffers will exceed the available memory and require external storage.

Perguntas sobre este artigo

How do I decide which of the 30 GPIO pins are free for my own circuits?

Some of the 30 pins are already used by the onboard LCD and sensors, so check the board's wiki for the exact pin map before wiring anything else.

What does the 133 MHz dual-core Cortex M0+ actually deliver when the board is running?

The RP2040 can execute code at up to 133 MHz across both cores, giving enough headroom for real-time sensor reads and smooth graphics on the 240×240 display.

What does the Type-C connector support on this board?

The USB Type-C port provides power, data and programming access for the RP2040, and it also feeds the lithium battery charge circuit.
