In 2022 the libraries associated with this seem to be left to die

I've spent the past afternoon trying to get this going. I've had to find an ancient version of adafruit's circuit python (V5) in order to get anything out of the screen at all and when I do connect everything, things don't seem stable.

I can't find V4 for my M4 Express, despite this being the suggested board, and Adafruit, now on V7, don't support circuitpython this far back.

Sorry Pimoroni, but this isn't good enough. If you're selling expensive boards, hire a dev to update the libraries if you need to.

I bought this a month ago and am deeply dismayed that it's completely incompatible with the recommended boards.

I am afraid the "problems" started at product launch and you can check #5 .

You likely invested a lot of time (soldering, trying to run the code) and money with this board, the PMS5003 sensor, one of the recommended Feather, some FeatherWing Doubler, maybe a Lipo... and the result is an almost unusable board or that require a lot of effort.

Personally, I gave up after spending some time to try to improve the situation. The specific hardware is collecting dust. People like @kevinjwalters may have continued and made it work for them and friends...

CircuitPython is an ecosystem, this product did a few things very differently (pin mapping) and did not try to maximise the reuse of existing library nor to keep up with CP version.

I am confident it is possible to do something with this board, but it require a lot of work, and you rightfully expect that at least some demo code can be run just by following the documentation.

The problems I saw or remember:

• Only work with a very limited number of Feather MCU because of the port mapping library
• Make use of every pin and make it impossible to use AirLift to upload data in wifi
• Not following and making sure it still work with new release of firmware and library
• Not using existing library where available or not submitting to the Library Bundle for library unique to this board
• The product page does not give a warning on the current state of the software for that product

Maybe contact the support, go on Pimoroni Forum and check for open thread or create a new one, check the related open and closed issue here and for each library, submit more specific issue for each individual problem, reports here on your finding. Worth case, try to send it back and have a refund. You could also leave a bad review, to warn other customer of this situation...

Good luck

I've not used mine recently but I looked back at my articles and I used CircuitPython 6.0.0 for first and then 6.2.0 when I showed how to use a Sensirion SCD-30 over i2c with it.

• Instructables: Using the Pimoroni Enviro+ FeatherWing With the Adafruit Feather NRF52840 Express
• Instructables: Plotting Carbon Dioxide Levels With the Pimoroni Enviro+ FeatherWing and Adafruit SCD-30

My aim there was comprehensive docs to get going with them and I fixed some bugs in the PMS5003 library.

I've gotten it working before in the past, and this thread inspired me to get it up and running again. I have it working on CircuitPython 7.1.1 on an m4 feather. I dumped all of the libraries I'm using into a repo. https://github.com/Oakwright/m4feather

Thank you @Oakwright! I was able to get my enviro sensor and m4 express running with your repo!

If anyone else is still having trouble with this issue what worked for me was using Circuit Python 5.X.X. It seems like newer versions of Circuit Python are just not compatible with the pimoroni libraries.
