Hi folks, Just received some of the new LED shims and after doing a full install via curl and making sure i2c is on I’m getting the following error in my code: ledshim.clear() ledshim.set_pixel(0,255,0,0) ledshim.show() Traceback (most recent call last): File “”, line 1, in File “/usr/li…

@gadgetoid Well I tried wiggling… but without any luck. I then decided to remove the pi from my project and re-solder the specific i2c pins and power/ground pins (on both pi zero and pico HAT) as indicated here: https://pinout.xyz/pinout/led_shim I then tried testing the LED Shim on the pi zero h…

Yeah, I have a couple of headers here that are on the flimsy side, really easy to bend the male PINs. I’m pretty sure the pins are thinner than they should be. They mate with female GPIO headers OK if your careful plugging them in. I’d be very surprised if they worked with something like the LED shi…

@gadgetoid Well… long story short… I finally got the LED Shim to work. The solution required some judicious header pin bending, specifically GPIO pins 2 and 3 (the i2c SDA and SCL pins). Simply wiggling—or bending and holding the shim itself in various positions—did not result in i2cdetect regist…

[image] Blanchot: I finally got the LED Shim to work. The solution required some judicious header pin bending, specifically GPIO pins 2 and 3 (the i2c SDA and SCL pins). cringe - yikes! Yeah this should not be necessary at all. The holes are very finely tuned on the SHIM header, and I think t…

@gadgetoid Thanks for your reply… I should also mention that I believe the 3 that I just received were probably from the ‘latest batch’ i.e. when I first noticed the shim for sale you were already ‘out of stock’. As soon as you had them back in I made my order…

Just ordered an LED shim. Won’t have it for a week or more though, snail mail. I’ll be soldering mine to the Pico Hat Hack3r board. I’ll be using the mounting holes on Pico Hat to mount my LED shim behind a Ninja Diffuser. Then a male 90 degree header on the other row of GPIO pins of Pico Hat. Then …

Got my LED shim yesterday. I have it mounted to Pico Hat hacker, that will let me mount it behind a diffusor. Stand offs on the Pico Hat hacker board. I put male headers on the back of the Pico Hat Hacker. I’ll use female to female jumpers to connect it to my Pi. I was getting an IO error until I w…

Glad to hear that you haven’t experienced any problems using yours as a solder-less shim. I have two in use at the moment—but have had no luck using either of them as they were intended—i.e. both have now been soldered to female headers. From the looks of it, it seems no one else has had trouble wi…

JFYI, I soldered mine. Its soldered to the Pico Hat hacker board with a male header. I didn’t solder all 40 pins though. For the most part I only soldered the pins actually used shown in the GPIO pinout. And all the ground pins, that was more to just to hold it firmly in place and add rigidity. From…

Got my project all done up, LED Shim as a thermometer
This is one nice bit of kit for the price.
