Original Gravity: Digital Capacitive Touch Sensor For Arduino – PartsCountry

Description

This is a small DC – DC boost module that converts a 0.9 ~ 5v power source to standard 5V, making it capable of supplying power to an Arduino microcontroller and other small electronic devices that use a 5v input. It integrates a PFM DC-DC boost control chip. The maximum output current is up to 500 ~ 600 mA. There are two power input ports, PH2.0 and KF235-3.81-2P which are compatible with DFRobot’s 3.7 V lithium battery.
