ESP32 CW Transmitter
Just a quick video today where I build a simple ESP32/si5351 based CW transmitter using a trio of BS170s in the finals. I am assuming most people aren't interested in a code walkthrough - let me know in the comments if you are interested in the code.
Here is the schematic and code

Here's the site I used to create the low pass filter

I got the debounce code from this reference.
