Pretty sure I fucked up, hoping I can salvage without having to throw more money down the drain.
Doing a electronics project that necessitated an assload of radiometric hall effect sensors and a microcontroller to read 'em. Bought a Teensy 4.0 (https://www.pjrc.com/store/teensy40.html) and >30 A1302 hall effect sensors (https://media.digikey.com/pdf/Data%20Sheets/Allegro%20PDFs/A1301,02.pdf). The problem is the operating range of these hall effect sensors is 4.5v to 6v, so they're made strictly with 5v logic in mind, but the Teensy is strictly 3.3v and explicitly does not do 5v on its pins.
The only way to fix this seems to just eat the >$30 (Bought more for a future project as well, so that number is closer to $50) and buy a different set of radiometric hall effect sensors, but it seems like a utter waste of about $50 to have a bunch of sensors I can't do shit with.
Is there any way electrically I could make this work, maybe with some resistors or some shit without just burning more money?
