The Big Nugget is best for high current projects needing long runtime from a battery source. It’s great for Raspberry Pi, BeagleBone, Arduino, IoT, and more.
It can power a Raspberry Pi drawing 1A for about 7 hours. An optional header allows you to connect larger batteries for extended runtime.
The input can provide power to the output and charge the battery simultaneously. When the input power is removed, the battery supplies power to the output.
I2C is available for checking battery capacity and voltage. It can also be used for adjusting settings such as max charge rate and input current limit.
The Big Nugget v2 is based on the Texas Instruments BQ25703A power management IC and the AOS AOZ2261 buck regulator.
