The ESP8266 doesn't have hardware PWM, and only a single ADC channel, both which can make it unfit for a lot of tasks.

That said, it does come with a lot of SRAM and the wifi/bt connectivity is obviously great.

The only very slightly more expensive ESP32 boards have 18 ADC channels, 16 PWM channels, and 2 DAC channels.

Yeah the ESP32 is pretty darn awesome.

There are actually hacky ways to work around that using DMA but yeah. Software PWM sucks.

I recommend trying the ESP32 as well (more pins for ADC and a few other features).

Either way, the ESP's are an incredible value (I use both).

Same. I have a bin full of esp8266's that have become my go-to for little projects. Going to play with esp32's when I run through them
