CircuitPython nRF52840 & Raspberry Pi Tutorial

A quick introduction to CircuitPython. A Raspberry Pi will be used to load the bootloader on a Nordic nRF52840 board and run the Mu IDE. Adafruit Blinka will also be used to demonstrate code compatibility between the Pi and the microcontroller. Code demos include GPIO and BLE.

All the code, schematics, notes and updates are available on my website:

This is the 1st video in my CircuitPython tutorial. Here's a link to the full playlist:

UPDATE: Adafruit has made extensive changes to the CircuitPython BLE library. Please see my website for updated code (link in description).

1) awesome video! 2) Dan and Scott are heroes when it comes to responding to users 3) my FAVORITE feature of CircuitPython is that literally anytime anything's broken or a feature you figure out you want is missing, when you ask, the answer is "oh yeah it's in <a version you're not up-to-date with yet, or the current beta>"

Finding Python and Micropyton a pure gift having trundled through Arduion IDE/C++. So intuative, simple to read and write, just a breath of fresh air for a non-programmer. Your tutorials are a gift, superbly put together and "fast pace" makes them superb reference guides, Thanks!

Man I have been struggling to learn Nordic SDKs for over a year now, and they are really a headache. Never heard of circuitpython before but it looks much easier than getting ble example form the nrf sdk to work. Great work! please make more videos on circuit python. Thanks a million

[BrandInman]

This video really helped me out. Thanks so much!

More BLE videos please! Great content.

[larsfagerbakke]

Wow! This was very useful! More BLE video please :-)

Love your work. Would love more videos on Python/BLE anc connecting Pi/microcontrollers to BLE devices and read/write data. Would like to hack my Xiaomi Mi Band 3.. Thanks again

[unarvuiot]

Very nice video, thanks, I am new to CircuitPython and nRF52840, please make more on CircuitPython and BLE

[scolic]

Incredibly useful, thanks for this video.

8:29 "Unfortunately everything is working, I was hoping for more debugging..." In all my years... I have never heard anyone say this before. LOL

[TheOldBlackCrow]

Great video. Thanks!
I'm looking to send analog sensor data from the nRF52840 Express to the raspberry pi zero via Bluetooth. Do you have any resources you can share? I have the code for the 52840 going out... But can't find python code for the Pi to receive it. Thanks again!

I have problem my nrf52840 not appear as removable disk after double tap ... what is solution please ?

[pjaro]

I would like to build a zigbee node with sensors based on raspberri pico. But even pico dont contain BLE, low power wifi or zigbee/matter protocols. Did anyone program communiction between pico with nRF52840 board by UART ?

[kevilay]

Would it be possible using the ble on the nrf52 board to actually send a analog input from the nrf52 ADC to a raspberry Pi python script ? Essentially a Bluetooth remote ADC.

Why is the charging battery LED blinking all the time? It is very annoying. Is anyway to turn it off when we are not using or charging a battery?
