I have a project where I need to control multiple L289N bridges. L289N bridge requires HIGH input to be at least 2.25V+ Which according to documentation Photon should be able to drive. However my D0 to D7 pins output constant 1.35V on HIGH. Which is enough to trigger the L289N a bit (i hear a buzzing noise from the motor but no power yet).
Looking at Photon documentation it should be able to provide enough voltage on HIGH to drive these.
Is there a way to toggle output HIGH/LOW power or is my Photon broken. It’s powered by USB connected to my macOS elgato dock.
