Hi I am have the devils own job getting the plasma 2350 W to work any help or advice would be most appriciated I have tried all the uf2 files i can find but it just will not work
This one will get you the correct firmware and all the examples.
https://github.com/pimoroni/plasma/releases/download/v1.0.0/plasma_2350_w-v1.0.0-micropython-with-filesystem.uf2
What RGB strip do you have, how is it wired, and how is it configured in the example?
Thanks for the prompt reply
I have the Flexible RGB LED Strip (aka NeoPixel, WS2812, SK6812) connected to the 2350 and the uf2. file that you shared installs on the board the board shows up in device manager but when I try to cofigure Thonny it throws an error that it is unable to connect to the com port with this error
Unable to connect to COM10: could not open port ‘COM10’: PermissionError(13, ‘Access is denied.’, None, 5)
If you have serial connection to the device from another program, then disconnect it there first.
Backend terminated or disconnected. Use ‘Stop/Restart’ to restart.
I only have the board in the usb
I had that uf2. file downloaded already
I can run the leds on a pico but not with the 2350
What happens if you press the reset button while its connected to Thonny?
The cursor blinks on an empty shell and there are no files showing in the left hand pane
I have a Plasma 2350, it’s not a W though. It looks like mine is running,
MicroPython feature/psram-and-wifi, plasma2350 v0.0.9 on 2024-11-06; Pimoroni Plasma 2350 (LTE + WiFi) with RP2350
Type "help()" for more information.

I'm going to flash it with the newer one and see what happens.
The plasma_2350_w-v1.0.0-micropython-with-filesystem.uf2 worked Ok for me. Part of my strip lit up right away as it ran the included main.py file on the reboot. I had to edit my original saved main.py slightly to make it compatible and run. But other than that all was OK for me. Thonny saw it and connected just fine.
Just to confirm, you have the new Plasma 2350, right? Not one of the older Plasma sticks?
I am begining to suspect my pc usb port as when i plugged my phone in it went a bit haywire I’ll give it a go on my raspberry pi a bit later.
I’m not too sure how to do it but I’ll muddle through
Thanks for all your help I’ll let you know how I get on
OK, just wanted to double check. Mine is the non W, it has the SP/CE connector for the RM2 module, but no onbard wifi,
Well I sat down with a nice hot strong cup of tea and after a few minutes of tinkering I now have it working on my Pi there was a great cheer all round and a very happy Madasafrog
Once again thanks for all your help I am really pleased with the outcome

Powering it via USB can be problematic depending on how many LED’s are in your string and how bright you light them. An old school USB A port is limited to just 500ma of current. Exceed that limit and it can turn off the +5V supply to that port. A Raspberry Pi on the other hand, can supply up to1.2A to any one of it’s 4 USB ports. I run my Plasma 2350 with a dedicated 5V 4A supply wired to the screw terminals. I have a 144 LED strip that I use for desktop lighting. I use a custom Data only USB cable for programing it. That way my dedicated supply doesn’t backfeed it’s +5V to the PC via the USB Cable.
Yeah I have a 5v power supply i can use . Did you make the data lead yourself or are they readily available?
I made it myself. I carefully cut a slit in the jacket length wise, pulled the red +5V wire out, and cut it in half. Then slipped it all back in and wrapped a piece of electrical tape around it. I used a yellow colored USB cable, the wrap of black tape really stands out to remind me of what that cable is for. ;)
yep that would do it I’ll spend a bit of time down the shed a tinkering see what i can manage. Great tip thanks again
