RP2350-GEEK Board with 1.14" Color LCD and USB Debugging

Jargon buster

Plain-language definitions for the technical terms used above.

Arm Cortex-M33

A low-power Arm microcontroller core designed for real-time control tasks. It matters because it can handle timing-sensitive jobs such as reading sensors or driving motors while the main processor runs Linux.

I2C

I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.

IPS

IPS is a type of LCD panel that keeps colours and contrast more consistent when viewed from an angle. This matters for small displays that may be mounted in a dashboard, handheld project, or enclosure where the viewer is not always looking straight on.

LCD

LCD stands for liquid crystal display, a screen technology that uses a backlight and liquid crystals to show images or text. It matters because LCD modules usually need a display driver and enough controller pins or a bus interface to send image data.

microcontroller

A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.

RISC-V

An open processor architecture used inside some modern microcontroller chips. It matters because it affects the software tools, performance, and low-power features available for developing projects on the board.

RP2350

A microcontroller chip from Raspberry Pi used as the main processor on some development boards. Knowing the board is built around an RP2350 helps you check software support, pin capabilities and whether it suits MicroPython projects.

SPI

A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.

SRAM

Fast temporary memory used by a processor while a program is running. More SRAM helps with projects that handle larger data buffers, networking, displays, or more complex code.

SWD

Serial Wire Debug is a two-wire programming and debugging interface used with many microcontrollers. It matters if you need low-level access to program, recover or debug the processor board connected to this carrier.

UART

UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
