I have this NodeMcu clone and just received my Pololo switch today, experiments show that only the following GPIO pins do not go high during startup:

GPIO5 (D1)
GPIO4 (D2)
GPIO15 (D8)

I have now verified this library works with an esp8266 (NodeMCU clone), see Using the Library on an ESP8266

I looked around for an option to do that, but could not find one, maybe an Admin can do it?

thanks,

I have updated this library to use machine.I2C instead of pyb.I2C, so it should now work on all MicroPython hardware, though I have only have a pyboard to test with. Let me know if you successfully use it with other hardware.

What are the pros and cons of using the machine.I2C or pyb.I2C libraries? Looks like machine.I2C is more 'portable' across the different hardware that MicroPython can run on? Are there any other considerations?

thanks,
Chris

https://github.com/chrisb2/pyb_ina219 I have written this library based on one I wrote for the Raspberry Pi. It supports the INA219 voltage, current and power monitor sensor from Texas Instruments. The intent of the library is to make it easy to use the quite complex functionality of this sensor. It...
