I'm assuming it would also be ok to connect both VCC and VDD to 3.3V.Pi GPIOs are 3.3V. VDD needs to be connected to 3.3V not 5V.PRO TIP: In many cases, you can just short VCC and VDD together. If your microcontroller uses 3.3V logic however, you'll want to connect VCC to 5V and VDD to 3.3V.
It might be a bit less accurate, but it should still work, right?
