I am powering a Xenon board via the USB connector and trying ti use the EN pin as an “on/off” switch.
When I measure the 3.3V pin on the Particle Xenon with the EN pin grounded, I see 1.0V not 0V as I expected. It reads 3.3V and operates normally if EN is not grounded.
Am I misinterpreting the function of the EN pin? I thought ti disabled the regulator and 3.3V should go to 0V to effectively "turn off " the board.
BTW -I checked an Argon board and found the same behavior.
