This is with on/off switch voltage boost module.The master chip is FP6291GLR
Can used the input voltage (VIN or GND)control the switches,also use MCU IO control the switches.
Control current is very small, MCU IO port can be directly controlled. Including micro-controller : ARDUINO UNO MEGA2560 AVR STM32 ARM PIC AT89C51 STC MSP430 FPGA CPLD etc.
When the EN pin = GND（OR MCU LOW level),the boost module is working properly;
When the EN pin = VIN(or MCU HIGH level,3.3V/5V) OR Not Connected(or MCU High impedance),
the boost module into standby mode, stops working, the output voltage is 0V(Can measure the output voltage is 500~800MV, which is inductive output voltage,you does not have to bother).
