How to power and connecting a Ticket Pro 5V to Neopixels

Post by everblueguy »

I have purchased a Datafruit Trinket Pro 5v so I am trying to find instructions on how to connect it to a NeoPixel strip. How many Neopixes I can use and what time of power can I use on this device (of course depending on how many pixels I use). As usual, I used an Arduino Uno to download the decoding to make sure it works, then I can download it into the Trinket. The reason I am using a Trinket is that it is small enough for my costume.

Thank you

David,

Thank you for providing me with the links. Unless I have overlooked this, I did not see a diagram on how to connect the Neopixels to the Adafruit Trinket Pro 5v. I was trying to find out how to connect the Neopixesl to the Trinket and find out how to power them but I did not see anything. It only shows info on the Neopixels and a separate link to the Trinket Pro but no connection info.

Here's an example project using neopixels with a Trinket Pro 5v https://learn.adafruit.com/re-boots-ani ... boot-laces.

The old trinkets are a bit problematic with the USB on modern computers as stated right at the top of the product page:
Deprecation Warning: The Pro Trinket bit-bang USB technique it uses doesn't work as well as it did in 2014, many modern computers won't work well. So while we still carry the Pro Trinket so that people can maintain some older projets, we no longer recommend it.
If you do have problems loading code onto it, have a look at the QtPy SAMD21 https://www.adafruit.com/product/4600, Trinket M0 https://www.adafruit.com/product/3500, or Gemma M0 https://www.adafruit.com/product/3501.
