1. Using spring thimble interface design, suitable for Zero series motherboards2. The onboard lithium battery charging chip supports dynamic path management and the power supply is more stable3. The onboard boost chip can provide a stable 5V voltage output4. It can communicate through the I2C interface, measure battery voltage, current, power and remaining power and other parameters, and detect the working status of the module in real time5. The onboard battery protection circuit prevents overcharge, overdischarge, overcurrent and short circuit, and the work is stable and . 6. Onboard charging indicator, easy to check the battery working statusUPS HAT(C) is an uninterruptible power supply (UPS) expansion board specially designed for Zero series, onboard switching lithium battery charging chip with path management, boost chip and voltage and current monitoring chip, which can pass 12C interface Monitor battery working status.Product parameters:Product name: UPS power supply moduleOutput voltage: 5VCharging power supply: 5VControl interface: I2CBattery specification: 803040 polymer battery 1000mAh 3.7VThrough hole diameter: 3.0mmColour: blueMaterial: PCB+metalSize: 65 x 30mmPackage Contents:1 x UPS module1 x lithium battery1 x screw packOnly the above package content, other products are not included.Note: Light and different displays may cause the color of the item in the picture a little different from the real thing.
