Review on Power Management HAT Communication User Defined by Erick Bowers

Uses a Micro-USB connector, 2.5A limit. Use a USB-C connector instead, which would allow for a higher current limit and lower resistance, which would mean a lower voltage drop. The battery input is limited to 7 to 28V but only regulates 4.88V and drops to 4.75V under load. Pis don't like anything less than 5V and seem to prefer 5.25V. The documentation leaves a lot to be desired. You'll have to dig around to find download links, and no documentation comes with the device. Ports for the Arduino should be plugged in (or come with connectors to install) so the Arduino can be plugged in and not soldered. for those who don't have a soldering iron or want to replace the Arduino if needed or needed. I'm only giving a few stars because the overall concept of the hat is great, but someone didn't give it. Think about it, it feels like it went into production. Improvements could also include the ability to charge a connected battery, although in my case the ability to charge is not required as I plan to connect a 7-28V input to the vehicle, although an option to charge would be nice contain the ability to recharge. updates. A BIG downside for a hat that doesn't have a charge controller is that the power going to the hat is ALSO going to the battery connector! If you use disposable batteries, this is a potential fire hazard! I'm reducing my rating to 1 star after this find! If there is no charge controller, it must be fitted with a diode to prevent connected batteries from being fed back! This is my first review, still working to find out the rest. Cap.
