Welcome to the latest Python on Microcontrollers newsletter! July 4th came in with a bang! Not the US fireworks or the British election, but a quiet roar from the folks at Raspberry Pi, who released a new version of Pi OS. And speaking of new releases, CircuitPython 9.1 is very close with a new beta. I hear Bluetooth for ESP32-S3 is getting love. PyCon Europe is this week, it should be fabulous, and catch the released videos from PyCon US. And much more as usual for your perusal. – Anne Barela, Editor

We’re on Discord, Twitter, and for past newsletters – view them all here. If you’re reading this on the web, subscribe here. Here’s the news this week:

10 Best Operating Systems for Raspberry Pi 5

10 best operating systems for Raspberry Pi 5

Over the years, Raspberry Pi boards have taken over the DIY projects landscape and have become synonymous with the term SBC. But despite their standalone nature, one still needs an operating system to drive every mainline entry in the Raspberry Pi family.

Fortunately, there are a lot to choose from, as these tiny boards are compatible with a good number of operating systems. Having spent a long time tinkering with a RPi 5, here are ten of XDA’s favorite OSes you may use on the latest member of the popular Pi family – XDA.

New Boards Supported by CircuitPython

The number of supported microcontrollers and Single Board Computers (SBC) grows every week. This section outlines which boards have been included in CircuitPython or added to CircuitPython.org.

This week there was one new board added and three more in progress.

Note: For non-Adafruit boards, please use the support forums of the board manufacturer for assistance, as Adafruit does not have the hardware to assist in troubleshooting.

Looking to add a new board to CircuitPython? It’s highly encouraged! Adafruit has four guides to help you do so:

What’s the CircuitPython team up to this week?

What is the team up to this week? Let’s check in:

Dan

I’ve finished fixing BLE bugs for now for CircuitPython 9.1.0, and am looking at the remaining issues. I released CircuitPython 9.1.0-beta.4 last Wednesday for further testing. It has the BLE functionality we wanted to provide: BLE central and peripheral, and bonding and pairing. Thanks to Scott for finishing the implementation.

Jeff

I’m working on a guide for MP3 playback that will cover the recently added ability to stream MP3s directly from a web server on most Espressif-family WiFi MCUs with PSRAM, including ESP32, ESP32-S2 and ESP32-S3.

Scott

This is a short week for me. I’m sick too so I’m not getting a ton done. However, I’ve loaded the Matter specification PDF onto my eink tablet to read through it. I’m excited to dive back into home automation.

Liz

This week I worked on a product guide for the new Adafruit Feather RP2040 Adalogger. This is another RP2040 “bones” board with a microSD card slot on the back. This makes it easy to add data logging or removable storage to your project. The guide has pages for pinouts, power management, CircuitPython, Arduino, factory reset and resources for download.
