Just watched a video short(AI generated I think) referring to ESP32 as "E S P 3 2" (Three Two) 😶

Do you pronounce it as "Thirty two" or "Three Two"?

Rust has been gaining traction for a few years, and it's becoming more usable in the #embedded space. In my latest series, I cover the basics of #Rust and build up to using it on an #RaspberryPiPico 2. Check out the first video here:
