SparkFun MicroMod Cellular Function Board - Blues Wireless Notecarrier

Jargon buster

Plain-language definitions for the technical terms used above.

API

An API is a software interface that lets a program control hardware or features provided by the operating system. In this product, API support matters if you want your software to adjust display settings such as brightness or contrast automatically.

DFU

Device Firmware Update is a mode that lets you load new firmware onto a board over USB. It matters when recovering a board or installing firmware without using a separate programmer.

GNSS

GNSS stands for Global Navigation Satellite System, covering positioning systems such as GPS and similar satellite networks. It matters here because high-precision GNSS modules can output lots of serial position data that this product can send wirelessly to a computer or phone.

GPS

The US satellite navigation system used by GNSS receivers to calculate position and time. Support for GPS is important because it is widely available and often used together with other constellations for more reliable positioning.

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.

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.

LED

A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.

M.2

A compact edge-connector format commonly used to plug small modules into a carrier board without soldering. On this product it is the physical connector used by the MicroMod system, so compatibility with the matching processor board is important.

MicroMod

A modular board system where a small processor board plugs into a separate carrier board that provides connectors, power, and peripherals. It matters because this carrier board needs a compatible MicroMod processor board before it can run your project code.

RGB

Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.

u.FL

u.FL is a tiny snap-on antenna connector often used on compact wireless boards. A board with u.FL usually needs an external antenna, which matters if the product will be inside an enclosure or needs better antenna placement.

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 Type-C

A reversible USB connector used for power and data on many modern devices. On this kit it indicates an alternate 5V power input, which may be useful for setup or charging without the solar panel.

USB-C

A modern reversible USB connector used for power and data connections. On this product it matters because it can connect directly to a computer as well as to a microcontroller project.
