RP2350 2" Touchscreen Board – 240x320 IPS, Camera Interface

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.

GPIO

General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.

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.

IDE

Short for Integrated Development Environment, a program used to write, run and manage code. It matters because some learners prefer a traditional coding workspace instead of a guided notebook-style lesson.

IoT

Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.

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.

MicroPython

A version of the Python programming language made to run on microcontrollers. It matters because it lets beginners write readable code to control LEDs, sensors, motors and displays without needing to start with lower-level languages.

OV5640

A specific camera sensor chip that captures still images or video data for a microcontroller or processor. The exact sensor matters because code examples, wiring, resolution, autofocus support and data format depend on the chip model.

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.

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.

USB mass storage

USB mass storage is the standard USB device class used by many flash drives and external storage devices. If a board supports it, your project may be able to read and write files on compatible USB storage, provided the software library also supports the device.
