Product description
Compact and smart module to keep powerbanks alive that otherwise shut down in order to save power. Suitable to use for low-power projects powered by 5V from a powerbank. The module draws power intermittently so it does not draw power unnecessarily. The pulse time is adjustable with a potentiometer from approx. 4 seconds to 45 seconds. Each pulse is approx. 100 ms long. The current consumption when inactive is less than 1 mA and when pulsed, approx. 70 mA (can be increased to 100 mA with solder bridge). D+/D- are bridged between the USB connectors so the unit does not need to be removed for programming or data transfer.
