Torch V5
Categories: Lighting
This is version 5 of the torch module with power-down switch. The power-down switch allows the module to power down and not use any power from the battery. This makes the battery last longer. The power-down switch is made of 3 transistors and is activated by the press of the button. it is deactivated by the microcontroller switching itself off. Once the device is switched off, it cannot re-activated itself but required a user to press the button again.
