The Adafruit TPL5110 Power Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of turning your project on/off using a built in timer that can vary from once every 100ms up to once every two hours. Basically, the TPL will turn on periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely turn off the power. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer.

The Adafruit TPL5111 Low Power Reset Timer is a stand-alone breakout that will turn any electronics into low-power electronics! It will take care of enabling & disabling your electronics using a built in timer that can vary from once-every 100ms up to once every two hours. Basically, the TPL will set an enable pin high periodically, adjustable by potentiometer or resistor, and turn on your project's power. It will then wait until a signal is received from the project to tell the TPL that it can safely disable the project by setting the enable pin low. If the TPL does not receive a signal by the set time-out, it will reset the device like a watchdog timer.

This breakout board will solve all your power-monitoring problems. Instead of struggling with two multimeters, you can just use the handy INA219B chip on this breakout to both measure both the high side voltage and DC current draw over I2C with 1% precision. With the internal 12 bit ADC (Analog-Digital Converter), the resolution at ±3.2A range is 0.8mA. With the internal gain set at the minimum of div8, the max current is ±400mA and the resolution is 0.1mA.
