System STM32 Special

via SparkFun: Commerce Blog

Hello there! In case you missed it, yesterday we released two new boards that feature the STM32 - one in our MicroMod Processor footprint, the other in the Feather-compatible Thing Plus. These are some of the most powerful, fast boards that we currently offer, so make sure to take a closer look at those!

Over the past week, SparkX also released two new boards: a new version of the ESP32 WROOM now with USB-C, as well as a QwiicNES Breakout that allows you to use a classic NES controller in your next Qwiic project. We finish off the day with two new LoRa modules that you can incorporate into a board that you design. Let's jump in and learn more!

Thing Plus or MicroMod? What will you choose?

SparkFun MicroMod STM32 Processor

SparkFun MicroMod STM32 Processor


The SparkFun MicroMod STM32 Processor is ready to rock your MicroMod world with its ARM® Cortex®-M4 32-bit RISC core! This little processor board provides you with an economical and easy to use development platform if you need more power with minimal working space. With the M.2 MicroMod connector, connecting your STM32 Processor is a breeze. Simply match up the key on your processor's beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all carrier boards). The STM32 is one of the most powerful microcontrollers available, so to be able to add it to your MicroMod Carrier Board is a huge advantage!

With a 32-bit ARM® Cortex®-M4 RISC core as seen above, the SparkFun STM32 Thing Plus brings power and precision to your projects. This Thing Plus comes flashed with the DFU bootloader, and to make the Thing Plus even easier to use, we've moved a few pins around to make the board Feather compatible. In addition, it utilizes our handy Qwiic Connect System, which means no soldering or shields are required to connect it to the rest of your system!

Thing Plus C - ESP32 WROOM

Thing Plus C - ESP32 WROOM


The ESP32 Thing Plus C is a comprehensive development platform for Espressif's ESP32. Like the 8266 and ESP32 Thing, the ESP32 Thing Plus is a WiFi-compatible microcontroller with support for both Bluetooth Classic (i.e. SPP) and Bluetooth low-energy (i.e. BLE, BT4.0, Bluetooth Smart), a Qwiic connector, and 21 I/O pins. Add to that a rich set of peripherals ranging from capacitive touch sensors, Hall sensors, SD card interface, Ethernet, high-speed SPIs, UARTs, I2S and I2C.

We took all the good from the original ESP32 Thing Plus and sprinkled on some more! USB C provides up to 2A, and it has an upgraded 16 MB flash ESP32 WROOM module, CH340 USB to serial IC, an onboard fuel gauge IC, and an onboard addressable LED perfect for as a multi-status LED. Oh, and the new taller reset and boot buttons are so much easier to push!

QwiicNES Classic

QwiicNES Classic


Did you know that the NES Classic Edition controllers look and feel very authentic to their original 1983 counterparts? The only difference is they're I²C compatible right out of the box! So we made this simple Qwiic-to-Classic adapter board to allow a NES Classic Edition to plug right in (using the Wii Nunchuck connector) and connect to your Qwiic compatible development board!

LoRa/FSK Transceiver Module - 915MHz (RFM97CW)

EDUvision EXTRA: Quetzal-1 Strikes Back

via Arduino Blog

We recently invited José Antonio Bagur to join us on EDUvision, to talk about his work on Quetzal-1; Guatemala’s first satellite. It was a hugely popular show with the Arduino and edutech communities, and we ran out of time before we could ask José all your space-based questions!

The range of questions you guys had around open-source, custom-built satellites were too good to go unanswered. So we brought him back for an EDUvision EXTRA. Melissa and Roxana teamed up to dig deeper into his amazing project.

Arduino EDUvision EXTRA about satellites and Quetzal-1

José Antonio Bagur, and Quetzal-1

You can check out José’s first interview, which took place during the EDUvision livestream. But to quickly get you up to speed, let’s give José, and his pride and joy Quetzal-1, a quick introduction.

He’s a mechatronics engineer, university researcher and professor from Guatemala. He’s no stranger to the Arduino community either, as he regularly joins the Arduino team to host the Spanish-language Explore IoT webinars.

There are no formal aerospace science education programs in Guatemala, so José and his colleagues really had their work cut out designing and building the country’s first satellite! Over 100 people were involved in its development, which, of course, made plenty of use of Arduino.

In the EDUvision EXTRA video interview below, you can find out all about the incredible work they achieved. He talks about how they managed to get it into space, how it works, and what kind of challenges they faced throughout the project. Feel free to add any other questions you might have in the comments, over on the forum, or on social media.

Oh, and you’ll also find out where the name Quetzal-1 comes from!

Enjoy this extra slice of EDUvision goodness, and remember to join us on 20th May, 2021, for the next livestream. If you have a project you’d like to see featured live on EDUvision, let us know all about it. If it’s picked to be showcased, we’ll even send you some free Arduino swag.

See you then!

QTPy-knob: Simple USB knob w/ CircuitPython

via Dangerous Prototypes

A how-to on making a simple USB media knob using rotary encoder and Neopixel ring:

I like minimal solutions to problems. I was playing with a CircuitPython-enabled QT Py on a breadboard with and a rotary encoder and I ended up making a USB knob, like many others have done before. But I realized: waitaminute, I can literally just plug the encoder directly onto the QT Py…

More details on todbot blog. All design files are available in the qtpy-knob github repo.

This DIY shuttle mission control box looks like a blast!

via Arduino Blog

Becoming an astronaut is probably one of the top careers on any child’s list, but it’s not all that practical, especially when they’re still seven years old. That’s why Gordon Callison wanted to create a virtual shuttle mission control game that simulates a space shuttle launch with tons of different features for his kid to use. 

The project he made is composed of many different panels that compose a box with three main surfaces that display/control various aspects of the shuttle’s journey. These include pre-flight checks on the right, launching the shuttle in the middle, and telemetry displays on the right. The whole thing fits neatly into a briefcase, but don’t let that relatively small size mislead you- it’s packed with plenty of LEDs and buttons. To control all of these, Gordon went with an Arduino Mega, along with a couple of shift registers for toggling a bank of 32 LEDs on and off. Sound effects can also be played through an Uno and Adafruit Sound Board whenever the shuttle takes off or is done orbiting. 

This system is a great showcase of what is possible by just using a bunch of simpler components, and Callison plans on expanding it even more with a possible fourth panel to show mock interior data. More details on the mission control box can be found over on Instructables.

Slot machine piggy bank makes saving your coins more fun

via Arduino Blog

There’s really no joy in saving money until it comes time to spend it, of course. But in an effort to gamify things a bit, YouTuber “Max 3D Design” has come up with a beautiful slot machine that surely puts a spin on traditional piggy banks.

The device itself was modeled in Fusion 360 and the fairly substantial design took a week of printing to produce. It features four LED matrices that rotate reel symbols, obscured by a thin film to make it appear as one display. Inside a screw conveyor system is used to transport coins, which eventually pop out of an opening at the end. This screw is actuated by a small stepper motor, and the gaming process is started by dropping a coin past a pair of wires under the control of an Arduino Uno.

If you want to create your own slot machine bank, more details can be found in Max 3D Design’s video below. The best part? By leaving it out in your home and letting family and friends play with it, you’ll save more money in no time!
