Geekworm Raspi UPS HAT Expansion Board for Raspberry Pi
Features: - Note: It's only a UPS HAT board£¬ you need buy a lithium battery(3.7V) to use it£¬ or you can buy the kits with battery; It's more convenient to replace more High-capacity battery; - Standard dimension of Raspberry Pi HAT£¬ and it's compatible with all of the expansion board. - Cascading design saves space while powering raspberry pi and expansion boards without affecting GPIO expansion. - Support up to 2A quick-charge technology£¬ can rapidly charge full the battery. - Can be charged and supplied power to raspberry pi at the same time. - With 4 LED power indicator; - Provides an example code to beginner to demonstrate how to demonstrate battery capacity displays the current battery level in the raspberry pi current program£¬ it can detect the current battery£¬ voltage etc. * Application scene 1: You can program to control automatic backup of data at low power and safe shutdown. * Application scene 2: Remind users to charge at low battery levels. etc.) - Removable battery£¬ user can choose a more larger capacity lithium battery pack (NOTE: voltage must be 3.7V). - With safety protection circuit to prevent overcharge and over discharge. - Retains the raspberry GPIO interface£¬ you still can use all kinds of expansion board; - It is Mini UPS power supply; maximum 5V / 2A output£¬ and maximum 5V / 2A input.
