Greetings:  
I have a Pimoroni Explorer for PICO.  
I transferred the UF2 program from Pimoroni into my new PICO.  
I downloaded the explorer “demo” program into the PICO and try to RUN the example and got the error file below.  
I also tried to energize the local LED on the PICO but got an error message as well.  
What am I doing wrong?  
Thanks  
Tom

If your running it from Thonny, you have to set the Interpreter to “MicroPython (Raspberry Pi Pico)”. How you do that depends on whether its Thonny on a PC or on a Pi.  
I’m not sure if that your issue, but its something to double check.  
On a Windows PC its Tools \> Options \> Interpreter. If Raspberry Pi Pico isn’t listed you need to install the latest version of Thonny. It’s what I had to do to get it listed.

I’m getting a similar problem having just bought a Pico and a Pico Explorer.  
Fresh install of Thonny on Win 10 laptop. Can run a simple script that makes the Pico onboard LED flash using the following script (saved as main.py on the Pico board):

_import machine_  
_import utime_  
_led\_onboard = machine.Pin(25, machine.Pin.OUT)_  
_while True:_

- led\_onboard.toggle()\*
- utime.sleep(1)\*

However, if I run the picoexplorer _demo.py_ from:  
**pimoroni-pico-main\micropython\examples\pico\_explorer** I get the error:

_Traceback (most recent call last):_

- File “”, line 2, in \*  
_ImportError: no module named ‘picoexplorer’_

I get the same experience if I attempt the above on a freshly imaged Raspberry Pi.

Basically, I presume at some point I need to install the missing modules - I tried _pip3 install picoexplorer_ but it’s not found on pypi.  
It is listed in **pimoroni-pico-main\micropython\modules** , but I don’t know how to install it from there…

Please help…

Which firmware are you running on the Pico, the one linked to on the Pico Explorer product page?  
I believe that you want to load the Pimoroni UF2 file.

Hi, I’m using the one from here: [https://www.raspberrypi.org/documentation/rp2040/getting-started/static/f70cc2e37832cde5a107f6f2af06b4bc/rp2-pico-20210205-unstable-v1.14-8-g1f800cac3.uf2](https://www.raspberrypi.org/documentation/rp2040/getting-started/static/f70cc2e37832cde5a107f6f2af06b4bc/rp2-pico-20210205-unstable-v1.14-8-g1f800cac3.uf2)

I’ve just replaced it with [https://github.com/pimoroni/pimoroni-pico/releases/download/v0.0.9/pimoroni-pico-micropython.uf2](https://github.com/pimoroni/pimoroni-pico/releases/download/v0.0.9/pimoroni-pico-micropython.uf2)

And it works!

Thanks Piratenik - I’m off for some Grog!
