Watt-A-Live: a power monitor shield and FeatherWing #Feather @HackadayIO @Tindie

Watt-A-Live Power Monitor Shield Wing

Via Hackaday.io, the Watt-A-Live is a power monitor designed as an Adafruit FeatherWing or Arduino Shield. It is based on the Texas Instruments INA209 with full connectivity to the unit under test.

It measures the load current through a shunt resistor and has separate ground connections to the power supply and the load to make it a true power monitor. 2 jumpers can select between 2 different shunts to measure different current ranges.

The board is populated with a 0.10 Ohm shunt to measure 3.2A to 100µA. Optionally a 500 Ohm shunt can be added for a current range of 640uA to 20nA. Maximum bus voltage is 26V.

Hackaday.io user MagicWolfi has a Tindie shop selling these boards, available here.
