Using CircuitPython with the 01Studio BLE Kit

So, let’s talk about MicroPython ! It’s basically a lighter version of Python, super cool for embedded systems where you don’t have all the bells and whistles of a desktop computer.
Instead of the usual coding languages like C that most people use for these types of projects, MicroPython lets you whip up some Python scripts to control your hardware – how awesome is that? Now, the focus here will be on CircuitPython , which is a variant of MicroPython designed by Adafruit.
They’ve really fine-tuned it to make programming hardware easier and more user-friendly.
Think of CircuitPython as a version of MicroPython, but it’s been adapted specifically for simplicity..

Let’s dive into the nrf-52840 Development Kit, shall we? This cool kit from 01 Studio, available through DeviceMart, uses CircuitPython to control all sorts of hardware.
At the heart of it is the nrf-52840, which packs a popular Bluetooth chip, making it super easy to control things like LEDs with just Python code.
You’ve got options, too, with modules for GPIO and an MCU, plus you can update your Python code via Jlink or USB.
For those looking to expand their projects, it comes bundled with a Jlink programmer and additional components divided into three handy packages.
We’re focusing on the Bundle 3 standard package and trust me, this kit has some exciting features—like built-in NeoPixels and buttons—just waiting for you to explore.
It even opens the door for connecting to expansion boards for more fun with peripherals and sensors!.

Setting up CircuitPython on your nrf-52840 is easier than you might think! First, swing by the CircuitPython page where you can search the download section for boards compatible with the nrf-52840.
You’ll want to grab the firmware made just for it so that you get the best performance possible.
Once you hook up your board to your PC using the Micro-B USB port, you’ll see a drive pop up named CircuitPy.
This means you’ve successfully got the CircuitPython environment all ready to roll! To keep things fresh, don’t forget to check the Boot-out.txt file on the drive to confirm which version is installed..

So, let’s dive into some fundamental programming concepts using CircuitPython! In the example we’re looking at, we’re making an LED blink and displaying “Hello World,” all while controlling hardware components.
To get started, we first import the Digital In Out library and set the pin mode—this step is super important for managing hardware.
We then configure the module’s LED as an output, making it blink every second.
This blinking acts as a handy visual cue that shows us the module is up and running.
Plus, this setup makes it really easy to keep an eye on things and troubleshoot, since you can see the LED’s blinking pattern change as you tweak the code.
We’re also using standard Python functions like Print and Sleep to make it all work smoothly with the nrf-52840 kit..

And just like that, the session wraps up with an exciting hint at more ways to control CircuitPython using the nrf-52840 kit in future chats.
The speaker is really looking forward to the next gathering, teasing a continuation of this incredible learning adventure..
