R-78E-1 Regulator: Solo Frame: $15    Double Frame $18

TSR 1-2450 Regulator: Solo Frame: $20    Double Frame $23


Available in Solo and Double variants, the Teensy Backpack Frame allows you to easily mount your teensy and provide external power from 8 - 28V! Both variants have four 2-56 mounting holes and a screw terminal for accepting 16-28 AWG wire. The Double variant stacks two teensy footprints side-by-side, enabling you to use more backpacks with a lower stack height.

Both frames include the R-78E-1.0 switching power regulator, which provides 1A of clean 5V power from a 8 - 28V input. Unlike linear regulators, switching regulators are very efficient, and this one has a typical efficiency of over 90%.

Optionally, our Backpack Frames can be ordered with the Traco TSR 1-2450 switching power regulator instead of the R-78E-1.0. The TSR 1-2450 provides 1A of clean 5V power with a wider input voltage range of 6.5 - 32V. This option is an additional $5 to either frame.

The Teensy Backpack Frame comes fully assembled and tested.
