I recently prepared to use DragonBoard 410 c development board debugging infrared, the infrared need 3-5 v voltage, I see on the gpio introduces development board as is the output of 1.8 v, can set the gpio port output voltage 3 v, please?

This need you adopt level conversion chip to complete, qualcomm main high performance, low power consumption chip can only output the GPIO 1.8 v level, but in drgonbaord 410 c board has a 3.3 v power supply, oneself welding derivation is ok, and then add a level conversion bridge can achieve 3.3 v output

It has three power supply way, the website has an introduction,
