Boron Voltage Compatibility

Check out this post… I faced this same dilemma a few months back:

16X2 Liquid Crystal Display (LCD) on Photon2/P2

So I'm quite familiar with particle but a complete Newbie when it comes to using LCDs and 5V vs 3.3V dynamics. To date, I've just always choose hardware that was 3.3V so I didn't have to think about it. However, I'm wanting to use a basic 16x2 LCD similar to this: These LCDs seem to all be 5V. I'm not constrained on I/O so figured I'd just use the traditional Particle LiquidCrystal Library and use the 6 pins on the LCD (RS, EN, D7, D6, D5, and D4) to any of the GPIO on the Photon. I also will …

I now have it working well on a P2. I assume same libraries and hardware can be used on the Boron as the P2 as both are 3.3V
