Back in our January 10, 2023 issue, we discussed the new ESP32-C6 and ESP32-P4. Now the C6 is on the market and Espressif has more P4 news.

Adafruit ESP32-C6 Feather

Adafruit has announced the Adafruit ESP32-C6 Feather, a C6 development board in the ubiquitous Feather form factor. It integrates 2.4 GHz WiFi 6, Bluetooth 5 (LE) and the 802.15.4 protocol. It brings the goodness you know from the low-cost C3 series and improves it with Zigbee/802.15.4 at 2.4Ghz. It could make for great Matter development hardware! There is also a BME280 temperature and humidity sensor onboard to make an integrated sensor node – Adafruit.

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 were two new boards added:

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 released CircuitPython 9.0.3 this past week to fix a problem with AnalogIn on Nordic nRF boards. I’m continuing to work on issues on the 9.x.x issue list.

Melissa

This past week, I’ve been working on updating Learn guides and their associated code. Some that I’ve updated include the Magic Storybook with ChatGPT guide, the Adafruit DPI Display Kippah guide, and the Adding a Real Time Clock to Raspberry Pi guide.

Jeff

I made enhancements to floppyio and adafruit_floppy to make it work better with the upcoming “floppsy” board. These changes are incompatible, so you’ll need different code for 9.0.x and older vs the unstable version of CircuitPython.

Scott

This week I put together my talk about wirelessly programming CircuitPython for PyCascades 2024. Once done with that, I switched back to working on USB host FeatherWing support. I have it working on nRF and ESP currently. Hopefully I can get SAMD and RP2040 working with it as well.

Liz

This past week I worked on a guide for the new SHT4x Trinkey. This Trinkey form factor board has an SHT41 or SHT45 temperature and humidity sensor onboard. I had a lot of fun with the demos for this one. I wrote up two CPython examples. One logs data from the Trinkey to a .CSV file and the other one logs data to Adafruit IO. I had never used the desktop Python Adafruit IO API but it was really easy to get up and running.
