Datasheet

The Trinket must be connected to a computer via a USB cable to enter bootloader mode. You can enter the

bootloader mode by pressing the little button on the board with your fingernail. The bootloader will 'time out' after 10

seconds, so to re-enter the bootloader mode just re-press the button!

Don't press-and-hold the reset button, be sure to press-and-release!

See the video below for what it looks like to plug it in, have the LED pulse in bootloader mode, time out and then press

reset to restart the bootloader

When the Trinket is in bootloader mode, the red LED will be pulsing. Once the red LED stops pulsing, you

must press the reset button to re-enter bootloader mode
