LORDWORLD RP2350-GEEK Development Board 1.14inch 65K LCD USB-A

SKU CH-9RPW-RDCD7

A development board with 1.14 inch 65K colour LCD, USB-A and TF card slot for debugging 3.3V Arm microcontrollers

  • Debug most 3.3 V Arm MCUs via SWD
  • 14 inch 65 K colour LCD for instant visual feedback
  • USB-A port enables direct host connection
  • TF card slot adds removable storage
  • Firmware-selectable SWD, UART or I2C interfaces

RP2350-GEEK Development Board

This development board targets engineers and hobbyists who need a compact tool for debugging 3.3V Arm microcontrollers. It combines a USB-A interface, a 1.14-inch 65K colour LCD and a TF card slot on a single PCB. The RP2350 microcontroller provides the processing core for custom firmware applications.

Installation and common issues

Connection is straightforward via the USB-A port and a 3-pin SWD cable to the target device. The main difficulty lies in selecting and flashing the correct firmware to expose the desired SWD, UART or I2C interface. Incorrect firmware choice or loose SWD wiring are the typical causes of a failed debug session.

USB-A and LCD practical limits

The USB-A connector supplies power and data but does not guarantee high-speed throughput for all firmware workloads. The 1.14-inch LCD offers a small viewing area suited to status text or simple graphics rather than detailed visual output. TF card performance depends on the card used and the active firmware's driver implementation.

Perguntas sobre este artigo

How can I confirm the 1.14inch 65K LCD is working after connecting the board?

The display should light up and show graphics or text once the RP2350 microcontroller runs firmware that drives the onboard screen.

What accessories come in the box and what must I source separately?

The board includes a USB-A port, 1.14inch LCD, and TF card slot; a 3‑pin SWD cable for Pico debugging and a micro-SD card are not included.

Which RP2350‑based version should I choose for 3.3V Arm debugging?

This RP2350‑GEEK model is the only variant listed and supports SWD, UART, and I2C debugging for most 3.3V Arm targets.
