The Great Search – Power Monitor with 2 Inputs

For our solar-capable Feathers, we're going to design a FeatherWing helper board to assist with solar connection and monitoring. To do that, we will want to monitor two voltages (the LiPoly battery and the solar panel) and one current (the panel draw). Traditionally, we've liked using the INA219 and friends—let's see if we can find a voltage/current monitor chip with an I2C interface and at least two monitoring inputs.
