Choose from seven lighting modes at . Button switching mode. the button to switch the light speed. Low power sleep mode achieves super standby capability. Key wake-up function Exquisite and compact, paired with button batteries, can be carried around Seven lighting modes and six lighting speeds, short the button once to change the lighting speed, short the button twice to change the lighting mode Kit Name: LED Shell Flow Light Production Kit Working current: 0.5mA@3V (All lights are on) 0.19mA@3V (One light is on) Maximum current: 1.5mA@3V (At startup) Sleep mode current: 0.4uA@3V LED display refresh rate: around 245Hz PCB size: 38.5mm x 50.6mm Six types of light speeds Short KEY1 to switch the speed of the light change. There are six gears for the speed change, which are: 1000ms, 500ms, 100ms, 50ms, 20ms, 10ms The speed changes from high to low with each of the button, and there is a power down saving function Display of seven lighting modes: Short KEY1 twice in a row to switch modes, with a total of seven modes and a power failure saving function Mode 1: Switching between D1-D10 in sequence Mode 2: Switching between D1-D10 in sequence, and then switching between D10-D1 in sequence Mode 3: Red light (D1D4D7D10), green light (D2D5D8), blue light (D3 D6 D9) switch in sequence Mode 4: The red light (D10) is always on, and D9-D1 switches sequentially Mode 5: Three lights D1-D10 light up simultaneously and switch sequentially Mode 6: Switching between D1-D10 in sequence, switching to the last light that stays on and stays on in sequence Mode 7: Six modes. Each mode is displayed twice and then switched sequentially It's DIY kits, needs to finish by yourself.
