<p>Do the 3.3V and 1.0V pins on the VL822 chips need to be externally powered or just linked together? I have seen conflicting things, some say that the chip has onboard LDOs that step the voltage down and those pins just need to be tied to ground via a capacitor but it seems like you are supplying them with external 1.0 and 3.3V power?</p><p></p><p>I would appreciate any help you could give :)</p>
