Hello, it’s been quite a while since I’ve worked on my project with Pixelblaze, but I just got my V3 plus expansion board and I had a couple questions before I go and solder them together. So, when you stack them together as pictured in the guide, the headers are supposed to line up directly. The important ones being GND, 3v3, and TX. Correct? Well on the Pixelblaze V3 the outputs go:
GND, RST, 3v3, RX, TX…
But then on the exp. board the inputs go:
GND, (space), 3v3, TX…
So if i directly set one on top of the other the RX from the Pixelblaze would be routed to the TX on the exp. board.
Is that correct or am I missing something?
2nd question. The guide says “Be sure to power the sensor board with 3.3 V - it’s not 5 V tolerant.”
Does the Pixelblaze take care of stepping down voltage from 5v to 3.3v? Or do I have to somehow power it separately? Just don’t wanna blow it up!
Thanks in advance, I have hopes of getting my project at least mostly up and on display by May. Can’t wait to post some videos of it. Also I’m really excited to work with V3, very thankful to Ben and anyone else that help make this awesome little controller, and for listening to the community and adding some really cool new features!
