Guided Tour
Let me take you on a tour of your Trinket! Each trinket is assembled here at Adafruit and comes
chock-full of good design to make it a joy to use.
Mini-B USB connector - We went with the tried and true mini-B USB connector for power
and/or USB bootloading. In our experience, Micro-B connectors can rip off the PCB easily, but
we have not had that problem with mini B, its much more rugged for DIY electronics. It's also
a proper USB connector, so you can use any length cable. Some Attiny85 boards use a PCB
that slides into a USB port to cut costs, but that makes it hard to re-program and annoying to
power with an external battery pack
Green Power LED - you'll know that the board is powered up when this bright LED is lit
Red #1 LED - this LED does double duty. Its connected with a series resistor to the digital #1
GPIO pin. It pulses nicely when the Trinket is in bootloader mode, and its also handy for when
you want an indicator LED.
Battery + Input - take your Trinket anywhere and power it from an external battery. This pin
can take up 16V DC input, and has reverse-polarity, over-curent and thermal protections. The
circuitry inside will use either the battery or USB power, safely switching from one to the other.
If both are connected, it will use whichever has the higher voltage
USB Power Output - You can also snag the 5V power from the USB jack in case you need
500mA+ current from your computer or portable USB power pack.
