Feizhai flashlight driven by 1.5A single cell lithium battery

Overview

The domestic chip STC8G1k08 is used as the main control, and the CN5711 constant current driver chip is used as the driver's flashlight driver circuit. Maximum current 1.5A, can be used for CREE L2 q5 SST40 XHP50.2 and other lamp beads

The advantage of bringing your own 51 microcontroller is that you can customize various modes, and the price is cheaper than the AVR microcontroller.
