“Good apart from the connector to Enviro+ that has a very poor connection. I carefully ensured from the start that I put the cable in the correct way round but it doesn't have a really solid fit to the red and black cable whereas the Enviro+ fits solidly to that cable.
Despite considerable 3 x building from scratch the Raspbian Buster and fully upgrading each time and taking on board ideas from Pimoroni discussions and a lot of ideas on Raspberry Pi Forum discussions; I only got the PMS5003 to have any data shown when I bolted together the Enviro+ to the Raspberry Pi Zero W v1.1 that came fully fitted with the 40 pin connector. I think it was freely given a few years ago by MagPi subscription. I never have used that Raspberry Zero W v1.1 before as I have many other Raspberry Pi Models in use: Zero, 1, 2B, 3 all in use and a Model 4 set up but barely used at present.”
