A 632832 lithium battery is pasted on the back to supply power to the "module-ESP8266" (it can also be combined with four 18650 batteries to form a power bank). TYPE-C, MicroUSB input, with USB-A output. Four-light mode power display, LED5 is used as lighting. Because IP5306 detects the output current regularly, if it is less than 45mA, it will enter standby. If the load is small, C5 can be replaced with a resistor of appropriate size (I use 470Ω to ensure that the ESP8266 module continues to work). If there is a better way to maintain output, please let us know.
