This is a V-USB development board meant to fit inside a metal (possibly scavenged) USB type-A shroud.
The thickness of the board and the shroud should be just about perfect to provide a nice, solid USB connection. The bottom layer also exposes traces that should be insulated from the shroud with kapton tape or similar. After all that, carefully superglue that lil' sucker inside the shroud. If you don’t want the ISP header, (or VBUS, GND, & GPIO pins) feel free to cut along the drills. The board /should/ be near flush with the edge of many shrouds.
Once the board is populated and firmware is flashed, it is software compatible with the Adafruit Trinket 5v. Rev A. successfully runs sketches in the same way a Trinket does - no extra steps required.
Notes:
- PB3 and PB4 are not broken out.
- D+ and D- are swapped from the Adafruit Trinket schematic, so you’ll have to alter the code to swap the V-USB pin assignments.
- It doesn’t have a regulator, a reset button, or any other schnazzy bells and whistles.
Changelog:
From Rev. A:
- Add LED on PB1 for bootloader status
- Tighter/smaller part footprints
- A narrower board that should fit in scavenged USB Type A Male shrouds
- Fiducial marks for machine vision
- Misc Layout improvements
