Forum: µC & Digital Electronics MCU with WiFi and GREAT ADCs

Hi,

I have been looking all over the Internet and the MCU that best matches 
what I'm looking for is the ESP32. However, those ADCs specs are not 
enough for my project:

I'm in need of a Microcontroller that has WiFi (integrated 2.4GHz 
antenna) and at least 12 input ADC pins (>=12 bit precision) with high 
sample rate (>= 1MSPS). These are the MOST IMPORTANT specs I'm looking 
for.

I don't really care much about the price, but I'm expecting something 
similar to the ESP products (~$10-15).

Thanks in advance!

thats not going to be easy, atleast I dont know of any popuplar and 
widely used module with those specs, there might be somethign available 
but most likely not available on a breakout board for <15€.

I would use an esp32/8266 with an external ADC (breakout board if you 
want to), also because the Wlan could disturb the ADC measurements and 
add noise.

What if I told you the price is not a problem? Any MCUs on mind? Of 
course,  I wouldn't want to pay for micros with LTE and stuff I dont 
need.

I specifically need a SINGLE board, so adding external ADCs is not 
possible in my case :(
