EnviroPlus-FeatherWing-1.0 library and CircuitPython 7.0.0


Are the EnviroPlus-FeatherWing-1.0 libraries compatible with CircuitPython 7.0.0 / Feather nRF52840 Express?

I assembled an Enviro+ Featherwing and Feather nRF52840 Express using a doubler but can’t get anything to display.

Using Mu / Serial connection to run code.py (test-all.py) I get:
MpyError: Incompatible .mpy file. Please update all .mpy files.

File “code.py”, line 9 in
Line 9.
Import pimoroni-physical-feather-pins

mpy is version 5.


Hi Matt,

I had some success last night having reverted to CircuitPython 4.

Having installed boot loader 0.6.3 and CircuitPython 4 I finally got the display to work. The adafruit_bme280.mpy exists in CircuitPython 4.

I also come across an instructables article (Using the Pimoroni Enviro+ FeatherWing With the Adafruit Feather NRF52840 Express : 8 Steps - Instructables) where more recent versions are used - will try these when I get the time.

Kind regards,
