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

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
