D4 is a constant, defined here: https://github.com/esp8266/Arduino/blob/master/variants/d1_mini/pins_arduino.h The ESP8266 GPIO pins do not always line up with development board pin names. D4 == GPIO2 Try replacing `D4` with `2`

Ask on https://forum.micropython.org/ and see if anyone else has experienced this. I don't actually own this board.

ADC3 pins: |pin|function| |-|-| |PF3|ADC3_IN9| |PF4|ADC3_IN14| |PF5|ADC3_IN15| |PF6|ADC3_IN4| |PF7|ADC3_IN5| |PF8|ADC3_IN6| |PF9|ADC3_IN7| |PF10|ADC3_IN8|

`public_key_to_address` can display the uncompressed address without creating a new `Key` instance. ```python >>> from bit import Key >>> from bit.format import public_key_to_address >>> k = Key.from_hex('0000000000000000000000000000000000000000000000000000000000000001') >>> k.address '1BgGZ9tcN4rm9KBzDn7KprQz87SZ26SAMH'...
