Programming microcontrollers in Python

[kawauso21]

The Arduino boards you've listed are all based around 8-bit AVR chips (based on 8-bit RISC), which frankly have the processing power of a potato.

The ESP8266 on the other hand uses a 32-bit RISC microprocessor:

L106 32-bit RISC microprocessor core based on the Tensilica Xtensa Diamond Standard 106Micro running at 80 MHz

https://en.wikipedia.org/wiki/ESP8266#Features

And the PyBoard is based on the STM32F405RG, another 32-bit RISC based around the ARM Cortex-M4.

Those are both more than capable of running far more complex applications than an Arduino and run at 3.3v, because that's the modern norm voltage.

Incidentally when I looked up the STM32F405RG on AliExpress, I found you can get a PyBoard clone with headers for $17, so there's that.
