So, i came across this little board and added to the shopping cart.
https://www.sparkfun.com/products/13907
Its features are very promising but if i read the datasheet correctly,
its programmable memory size is 520KiB ???
http://esp32.net/
Anyways, my ultimate question is that,
since it has integrated wifi and bluetooth
will these modules be automatically turned on once power is applied to
the board ? or they are turned on by initiating/calling certain functions ??
because i definitely would prefer the latter.
I'm asking because this is the first time i will be using an mcu with integrated wifi or bluetooth and wouldn't want to be working around a device that is constantly radiating.

Re: ESP32 bluetooth + wifi info
This isn't really a MicroPython question. The maximum transmit power is 14dBm under any WiFi standard bar the long obsolete 802.11b mode. BLE is lower at 12dBm.
14dBm is 29mW - by contrast your mobile phone emits 34 times more power (~1W) very close to your cranium. I am not a doctor but I think you'll survive![Wink ;)](./images/smilies/icon_e_wink.gif)
If you're running MicroPython the WiFi can be switched off. AFAIK BLE is not yet supported on ESP32.
