WizFi360-EVB-Pico RP2040 WiFi Development Board

Jargon buster

Plain-language definitions for the technical terms used above.

breakout

A breakout is a small circuit board that makes a tiny or hard-to-solder component easier to connect to with standard pins. It matters because this OLED module can be wired into a microcontroller project without needing to solder directly to the display’s fine contacts.

Flash memory

Non-volatile memory that keeps stored data even when power is removed. In this sensor, it matters because enrolled fingerprint templates can remain saved after the project is turned off.

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.

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.

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.

PCB

A printed circuit board is a rigid board with copper tracks that connect electronic parts without loose wires. For this kit, the PCBs also form the airplane shape, so they are both the circuit base and part of the finished model.

RP2040

A microcontroller chip used on many maker boards, with enough speed and flexible I/O for some camera and display projects. Compatibility with RP2040 matters because camera modules often need many pins and careful timing to read image data successfully.

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.
