The SparkFun AzureWave Thing Plus is a Feather form-factor development board equipped with the AW-CU488. The module features the Realtek RTL8721DM integrated single-chip low-power dual-band (2.4GHz and 5GHz) wireless LAN communication controller. It also consists of a dual processor core: Real-M300 CPU (ARMv8-M, Cortex-M33) and Real-M200 CPU (ARMv8-M, Cortex-M23). Connect the SparkFun AzureWave Thing Plus to the cloud to grab current weather conditions in your area, post sensor data to a server, control the lights in your next home automation project, or even calculate the Fast Fourier Transform (FFT) of an input audio signal!
Why the name? We lovingly call it the “Thing” because it's perfect for your Internet of Things project. The Thing does everything from turning on an LED to posting data with your chosen platform and can be programmed just like any microcontroller. You can even program the Thing through the Arduino IDE by installing the Realtek Arduino core.
The board includes a USB-C connector for programming and power. Two buttons for reset and boot are also populated on the board. For those that need to go remote with their application, the board includes a 2-pin JST connector and the MCP73831 single cell, LiPo charge IC (set to a default rate of 500mA). Voltage is regulated down for the AW-CU488 with the XC6222 3.3V/700mA voltage regulator. Three status LEDs are available for power, charging, and status. Due to the size of the module, the board is slightly longer than the standard Thing Plus footprint. With the added length, we were able to break out a few more PTHs on the edge of the board for a total of 30 GPIO pins (30 Interrupts, seven Analog, 11 PWM, two UARTs, two SPI, and a single I2C). The board also includes a built-in audio CODEC with two channel analog inputs and outputs at various sample rates (8/12/16/24/32/48/.../176.4 kHz). On the back of the board are five jumpers for the LiPo charge rate, LED, auto boot circuit, and USB shielding. Finally, one Qwiic connector is populated on the board to easily add Qwiic-enabled I2C devices to your projects!
Note: Additional items found in our photos are not included with the SparkFun AzureWave Thing Plus. You will need to purchase these components separately. Check the Hookup Accessories section below for options.
The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards use a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can’t hook it up wrong.

Jargon buster
Plain-language definitions for the technical terms used above.
- ADC
- An analogue-to-digital converter reads a changing voltage and turns it into a number the microcontroller can use. It matters when connecting analogue sensors such as light, sound, or variable-resistor sensors.
- 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.
- Headers
- Rows of metal pins used to plug a module into a breadboard or connect it with jumper wires. Pre-soldered headers make the module easier to use straight away without needing to solder the pins yourself.
- 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.
- 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.
- LiPo
- A lithium polymer rechargeable battery commonly used in portable electronics projects. It matters because LiPo batteries need correct charging circuitry and care, and this board includes hardware intended for that battery type.
- MCP73831
- A lithium battery charger chip used to safely charge a single-cell LiPo battery. It matters because it lets the board recharge a battery from USB or another input without needing a separate charger module.
- 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.
- PTH
- Plated through-hole means the pin holes are metal-lined so solder connects the pad on both sides of the board. It is useful for connectors and headers that need a strong mechanical and electrical connection.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
- Qwiic
- Qwiic is a plug-in connector system for I2C devices that uses small 4-pin cables, so you can connect compatible sensors without soldering. It matters because your controller or adapter also needs Qwiic, or you will need a cable or breakout to wire it up.
- 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.
- Thing Plus
- Thing Plus is SparkFun’s development-board form factor with a small rectangular layout and connections suited to wireless and battery-powered projects. It matters because boards and accessories in the same form factor are easier to mount, wire, and swap between projects.
- 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.
