## Questions & Answers

**Q: Is the ina219 chip marked b219, which is the higher precision version of the chip?  the a219 is the the lower precision one.**
A: Should work with it.

**Q: Should these work with the adafruit_ina219 library? i tried the two i received, and bus voltage always reports 1.0v, even with nothing connected.**
A: i used the adafruit library (Adafruit_INA219.h) and it seems to work. I built a volt/amp meter with an arduino nano and a little .9 inch screen.  I have done any calibration or fact checking on the accuracy of it, but it does seem to work with that library.  I started my build with the dronebot workshop (youtube videos that are GREAT) explanation of this ina219 sensor and then modified based on some other youtube builders.
