Happy to report SparkFun's main Teensy page is now showing all 6 models of Teensy 4.1 in stock. :)

I recently bought a Ground Loop Noise Isolator: https://www.amazon.com/dp/B06XQYN77L?ref=ppx_pop_mob_ap_share I’m guessing that using this with the headphone jack on the audio shield of teensy should overcome all ground related concerns.

Wonderful! What a coincidence that this is happening exactly when I’m looking to buy! Just out of curiosity, how was this timeframe chosen by spark fun?

Hello, I’m looking to order lockable teensy 4.1 NE in bulk. However, it’s shows ‘back order’ on spark fun. which has been the case for a while now. Any idea on when it’ll be back in stock? Is there a way to buy it elsewhere? Thanks, Tejas

Hello, I’m trying to accomplish serial communication between teensy and iphone using usb C. What’s the best way to achieve it? Thanks, Tejas

I checked with a spectrum analyzer. There is indeed a DC offset. I don’t know how to fix that though. Any help is appreciated! I have attached the .h file here.
