ESP32 Forum

Hello guys , need some solid advice on esp support for wearable devices, actually i'm building a smart watch and looking for some tiny and fast esp soc or module which can able to fulfill the requirements like ble, wifi. >100mhz fr., external sensors support, low power consumption and touch panel support.
i've found some soc's , (idk whether they are good for my purpose or not )
1. esp32-pico-d4
2. esp21 s2
please suggest if anything else is better..

The PICO is the smallest integrated solution.
Otherwise if you use the more "bare" mcu esp32 and external psram and flash, those two components are larger than the mcu itself.

I just saw this. I was waiting for the GPS version.
I wonder how they get those tiny maps in there
