A INA219 current sensor DIY Breakout board project from Juan Ignacio:
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.
