16 LED PWN, 18 ADC, 2 12C, 4 SPI (shares pin with GPIO)
D0WDQ6 is the standard package, D0WD is smaller
10.8x25.5mm, requires CP2102 USB to Serial
28.3x51.4mm, embedded mini-usb

To use the Bluetooth or BLE functionality of the ESP32, you will need to use the Espressif IDF not the Arduino IDE. ?

Which Processor can kill the ESP32? - YouTube compares with S2, S2 is a slight improvement upon ESP32
Pros: Wifi and Bluetooth, price, memory, many specializations
Cons: power hungry, Bluetooth 4.2 only, deep sleep causes a reboot, low quality ADC

Connect RST (RESET) pin to GPIO 16 (WAKE)
RST is high when ESP8266 is on, and RTC interrupt can pull GPIO 16 to low
so ESP8266 will reset based on timer and deep sleep again
use deepSleep(0) to let other input to pull RST switch to low
