I think it got damaged in the move, was intermittently turning off when I touched it. Found a couple broke cold solder joints.

That looks better.

Back to work! The G pin(fan) was the other cold joint.

@idlehandsdev What else is it doing that requires that other massive IC?

@jhiller No idea why they needed that size of a package

@idlehandsdev Esp32s are everywhere. The most popular light aircraft ADSB (anti collision) transponder uses it too and is FAA certified.

@McmillionNile Now that is cool

@idlehandsdev You'd be surprised at how many ESP32 you can find in product teardowns. They truly dominate the market with their rock-bottom price. Some competitor's prices can be up to 5x-10x more.

@alexlesuper It’s pretty crazy, odd they still put the other arm mcu in there.

@idlehandsdev Cheaper certification

@Derek2137 Definitely!

@idlehandsdev Lots of things use ESP32 according to the mac addresses.

@idlehandsdev Everyone is using esp’s now.

@idlehandsdev Esp32 is amazing 🤩

@idlehandsdev My Traeger has one too

@idlehandsdev I found an esp32 in two products with WiFi, I guess it's easier to make the connection. The main mcu is an ARM on both.

@idlehandsdev @DJSnM

@idlehandsdev And a good old 'F407 in the high pin count config presumably just for the 8080 parallel LCD

@idlehandsdev Soooo much cheap IoT stuff does. Emporia Vue does as well.

@idlehandsdev @mustafatan75 And chinese clone of stm32 :) i think, main processor gd32f407 and esp32 use for wifi/Bluetooth interface. Tcp ip stack needs more ram and flash. esp32 have more ram and flash but limited io, timer, ADC etc.

@idlehandsdev Redundancy, future proofing the platform for more compute capacity.

@idlehandsdev this company's faith in a facebook heaven has delivereth unto me many fold part sourcing.
