I need to connect NodeMCU and NRF24L01. Is this realisable with a ESP8266 (ideally with NodeMCU)? I realise that the software PWM of the ESP8266 has a maximum frequency of 1 kHz while the sigma-delta can be used to implement a PWM with a fixed frequency of about 300 kHz. Of course, if you want to run a program written in MicroPython on a NodeMCU independent of your PC and Jupyter, you must save your code as a "main. const byte sensor = A0; // where the multiplexer in/out port is connected.
