Another small board, this time for a INA219. The INA219 is a high-side current shunt and power monitor with an I2C interface.
For testing I used Rei VILO library with a MSP430G2553 and Energia, and I measured the power consumption for this simple circuit:
Nothing fancy, just a led and a resitor. The INA219 should measure around 9.6 mA and got this:
The current measurement is slightly off. I need to play a litlle more with the calibration routines.
