What pins to use on trinket pro versus original?

by theoneandonlymir on Fri May 07, 2021 10:25 pm

I'm attempting this circuit with the 5V Pro Trinket instead of the older version, and I'm not getting any power. I have everything properly soldered onto the pro trinket lipoly backpack but I'm not sure on the trinket 5V pro version where my USB, bat, g, and leds go since there's so many options. I'm sorry if this is a very "noob" question but I've recently go into lighting my props and this is all new to me.

The 'BUS' pin on the Pro Trinket is your USB bus voltage. Connect that to 5v on the backpack. BAT and G go to BAT and G.

Where do the LEDs go on the pro?

In the tutorial for the zelda guardian sword, they say to cut a trace on the backpack, how do I know if I did that successfully? I had the connections right according to what you said, and still no power.

Please post a photo showing all your soldering and connections.
