Neither the ESP8266 chip itself, not the ESP8266 modules, have a 3.3V voltage regulator. There is usually a voltage regulator on the development boards, but it varies between the board make and version, so there is no single answer to that.

Just use your NodeMCU and add an external ADC chip. For example, here is a library for ads1015, which has a lot of cheap breakouts available: https://bitbucket.org/thesheep/micropython-ads1015/

In theory, the "radio" module uses exactly the same protocol as NRF24 does, and it should be possible to have them communicate out of the box. In practice, I've spent several weeks trying to get that working, and failed — I only managed to receive about 1 in 1000 packets on the NRF24 side, and mangl...
what is the point of PyBoard, other than having a few more I/O channels and pins? The price is one important difference. But generally speaking, they are two completely different systems made completely different people working at different companies. PyBoard tries to be a general-purpose developme...

I have it, it's a TFT. An OLED display of this resolution (and color!) would need much more electronics on the back to generate by the high voltage necessary to drive a whole row of LEDs. While the low-resolution mono OLEDs get away with a simple charge pump, and only need external capacitors, somet...
